Banksy Street Works at Auction:
Between Illegality, Authenticity, and Market Reality
Before the editions, before the studio works, and long before the market embraced his name, there was the wall. Banksy’s practice is fundamentally rooted in the street, in interventions executed directly onto the fabric of the city, often without permission and always with intent. These murals are not marginal to his work; they are its foundation. Many of the most recognizable images that later appeared as prints or studio compositions originate from these public interventions, making the street not simply a context but the primary medium through which Banksy first articulated his visual language. To understand Banksy is therefore to begin with these works. They are immediate, site-specific, and inseparable from the urban environments in which they were conceived. They carry the urgency of the moment in which they were painted and the political or social tensions they were meant to expose.
A Category Outside the System
Unlike prints, paintings, or sculptures, Banksy’s street works do not come with certification from Pest Control Office. This absence is often interpreted as a lack of legitimacy, when in reality it reflects a deliberate structural boundary.
The Origin of Banksy’s Practice: The Wall as Primary Medium
Before editions, before studio works, before the market, there is the wall. Banksy’s practice is fundamentally rooted in the street. His murals, executed illegally or semi-legally in public space, constitute not only the most direct expression of his artistic language, but also the conceptual foundation from which much of his later work derives. Many of his most iconic images, later translated into prints or studio pieces, originate precisely from these interventions on urban surfaces.
To speak of Banksy without acknowledging the primacy of the mural is to misunderstand the work entirely. These pieces are not peripheral: they are the source. Banksy did not create these works to enter the market. They were executed in situ, often illegally, without intention of future sale, transport, or conservation. As such, the traditional mechanisms of authentication (requiring inspection, documentation, and controlled conditions) simply do not apply.
More importantly, formal authentication of street works would open a complex and potentially unmanageable field for Pest Control, involving logistical challenges, legal ambiguities, and questions of ownership that the organization has deliberately chosen to avoid. The result is a paradox: some of the most “authentic” Banksy works, those made directly by the artist, in the street, exist outside his official authentication framework.
Authenticity Without a Certificate: A Constructed Consensus
The absence of a certificate does not mean the absence of authorship. It simply means that these works exist outside the framework that governs Banksy’s market-approved production. In this context, authenticity does not disappear; it is constructed differently. Rather than relying on a single institutional authority, the attribution of a Banksy mural rests on a convergence of evidence that, taken together, forms a compelling and often convincing narrative.
Historical photographs of the work in its original location, documentation of its removal, provenance linked to property owners or intermediaries, and contemporaneous media coverage all contribute to this process. In many cases, the works were also documented on Banksy’s own website or through channels associated with his practice, further reinforcing their attribution. Visual analysis plays an equally important role, as the consistency of technique, stencil language, and iconography allows specialists to situate these works within the artist’s known corpus.
What emerges is a form of consensus, not decreed but assembled, in which authenticity is the result of accumulated evidence rather than formal certification.
A Market Both Real and Unresolved
Removal: Vandalism, Theft, or Conservation?
The removal of Banksy murals remains one of the most contentious aspects of this market. For many observers, detaching a work from its original setting represents a form of cultural appropriation, transforming a public gesture into a private commodity. These works were offered freely to the communities in which they appeared, and their extraction can be perceived as a violation of that initial intent.
Yet an opposing argument persists, and it is not without merit. Street works are inherently vulnerable. Exposure to weather, pollution, vandalism, and urban development ensures that many of them are destined to disappear. In this light, removal can be understood as an act of preservation, allowing the work to survive beyond the fragile conditions of the street and to enter collections, whether private or institutional, where it can be conserved and studied.
The tension between these two positions is not easily resolved. It is precisely this unresolved condition that gives these works their particular charge within the market.
The Emergence of a Specialized Market
Despite their ambiguous status, Banksy’s street works have developed a distinct and increasingly structured presence at auction. This market has not been driven primarily by the traditional major houses, but rather by more specialized actors willing to engage with its complexities, most notably Julien’s Auctions and Hessink’s.
Julien’s has played a pioneering role in introducing these works to the American auction landscape, presenting major murals as significant cultural artifacts and emphasizing their rarity and historical importance. Hessink’s, in turn, has approached the category with a systematic ambition, organizing dedicated sales and contributing to the construction of a coherent body of reference for Banksy’s street production. Through repeated transactions, these houses have transformed what might once have been perceived as isolated anomalies into a recognizable and functioning segment of the art market.
The market for Banksy’s street works is no longer speculative. Auction results demonstrate consistent demand, with prices reaching significant levels depending on the scale, subject, and provenance of the piece. Collectors are willing to engage with the complexities of the category, accepting the absence of formal certification in exchange for the opportunity to own a work that is, in many respects, closer to the artist’s original gesture.
Yet this market remains fundamentally unresolved. These works exist outside the artist’s official system while simultaneously being integrated into a commercial framework. They are supported by scholarship and market confidence but also surrounded by ethical ambiguity and conceptual tension. It is precisely this instability that defines their position.
A Parallel Authority: The Catalogue Raisonné
In the absence of certification from Pest Control, the development of a catalogue raisonné of Banksy’s street works by Hessink’s represents a significant evolution. Such a catalogue, when rigorously compiled, provides structure to a field otherwise defined by fragmentation. It documents works, establishes chronology, and offers a framework within which individual pieces can be understood and compared.
While it does not replace the authority of Pest Control, it introduces an alternative form of validation grounded in research, documentation, and expertise. In a market where official endorsement is unavailable, this kind of scholarly infrastructure becomes essential, offering both collectors and institutions a reference point upon which to base their decisions.
What Is Being Sold, Exactly?
What is being sold in these auctions is not simply an image but a fragment of the city itself. These works exist as sections of walls, pieces of concrete, metal panels, doors, or wooden supports that once formed part of a larger architectural context. Their physical presence carries the trace of their original environment, embedding the work within a history that extends beyond the act of painting.
To acquire such a piece is to acquire not only a composition by Banksy but also a material witness to its existence in the public realm. It is this dual nature, at once artwork and artifact, that distinguishes these objects from more conventional forms of artistic production.
The legal status of Banksy’s street works introduces an additional layer of complexity that cannot be overlooked. These murals are often executed without authorization, raising immediate questions about the legitimacy of their removal and subsequent sale. Because they are created on existing structures, ownership of the physical wall typically belongs to the property owner, yet this does not automatically clarify ownership of the image itself. In practice, it is often the owner of the wall who authorizes or undertakes the removal and sale, but this process sits in a legally ambiguous space where property rights, artistic authorship, and public interest intersect. As a result, each transaction carries its own set of legal considerations, making this category of works not only conceptually provocative but also juridically uncertain.
Conclusion: The Purest Banksys?
There is, perhaps, a final irony in all of this. The works that were never meant to be sold, that were created freely and often illegally, now circulate within a structured and increasingly sophisticated market. They resist certification, yet they are recognized. They challenge ownership, yet they are owned.
One might argue that these are among the most authentic Banksys, precisely because they originate directly from the street, unmediated and uncompromised. At the same time, their removal transforms them into objects that exist far from their original purpose. The question of legitimacy therefore remains open. The market has not resolved it. It has simply chosen to operate within it.

Stencil and Spray paint on Chipboard
Dimensions: 62x56x2 cm (24-3/8 x 22 x 7/8 inches)
The artwork was painted inside former German cargo ship ‘Thekla’, which was moored in Mud Dock, Bristol. The ship which was converted into a music and comedy venue in 1983 and by the mid 1990’s and early 2000’s it was operating as a nightclub. Banksy painted a number of works at the venue, most famously his ‘Grim Reaper’ on the hull of the ship in 2003, which was later transferred to Bristol Museum’s M Shed, a harbour side museum. The smaller ‘Running Coppers’ was removed from the ship during renovation works in 2006, and was salvaged by one of the site workers who was a fan of Banksy’s work. The site worker then approached Banksy for his permission to keep the piece and was verbally given Banksy’s blessing. One of a number of examples of this particular stencil, produced by Banksy in Bristol in 1999 and later in London. The piece depicts two British police officers in chase mode. Sprayed onto painted chipboard, the piece is quintessential Banksy, capturing a familiar sight in British life, with a few well positioned lines and his uniquely deft touch.

Banksy | Police Van Chimp London Turf War Exhibition Stencil Painting
BANKSY (British, 1974)
Untitled (Police Van Chimp), 2003
Aerosol on glass van window
Dimensions: 24×24 inches
An original aerosol painting on glass, executed by Banksy as part of his “Turf War” exhibition, which was staged in an abandoned London warehouse in the summer of 2003. Banksy’s “Turf War” exhibition widely considered his breakthrough, combined animal, political, and pop culture imagery: with live cows sporting Andy Warhol’s face; tethered sheep painted as if wearing concentration camp garments; and a crashed “police” van graffitied with subversive imagery.
One side of the van featured the words “Turf War” next to a painting of a gas-masked pig lighting a bomb, an anarchy symbol, and flowers. The phrase “Anarchy in the West Country” was sprayed across the other side of the vehicle. The rear of the van featured yellow and orange stripes on the doors, and the image of a chimpanzee staring out at the world from the rear window.
This chimpanzee image stems from Bansky’s artwork “Laugh Now,” originally commissioned by the Ocean Rooms Nightclub in Brighton in 2002. That work was a spray-painted mural featuring ten chimpanzees in a row wearing sandwich boards: some boards blank, some bearing the ominous message “Laugh now, but one day we’ll be in charge.” Following the “Turf War” exhibition, the underground performance group known as the “Prada Meinhof Gang” took possession of the van, intending to destroy it during a future live performance. The van was transported from the warehouse site by friend and fellow artist Mangrey, who ran a now-defunct pallet yard in the Clarnico Sweet Factory. Here, Mangrey removed the back window of the van as a memento and would retain it in his flat for the past 20 years. The van eventually returned to south London before disappearing completely.
This window is a rare original artifact from this groundbreaking exhibition, and a unique example of an original Banksy “Laugh Now” artwork, many originals of which have fetched high prices at auction. An acrylic and aerosol example on canvas sold for $2,280,000 USD in 2021, and a spray-paint and emulsion on paperboard example sold for $2,070,000 USD. Examples of the limited-edition prints of the chimp with sandwich board have sold for upwards of $90,000 USD. The significance of “Turf War” extends beyond marking Banksy’s emergence on the art scene: according to expert Richard Jones, it might also constitute the only on-camera appearance of the elusive artist. A man claiming to be Banksy was interviewed on video at the warehouse by ITV London’s Hague Gordon, with the van bearing the “Laugh Now – Police Van Chimp” clearly visible behind him.
Crazy Horse, 2013

USD 160,000
Banksy | Crazy Horse New York City Stencil Painting
BANKSY (British, 1974)
Crazy Horse, 2013
Aerosol on car door
Dimensions: 71 x 40.5 x 30 inches
An original Banksy aerosol painting executed on a car door, from the art installation “Crazy Horse.”
The installation, constructed near the corner of Ludlow & Stanton in New York City’s Lower East Side, consisted of two vehicles painted with a depiction of stampeding horses bearing down on a huddled group of terrified people, and included a phone number through which audio clips could be heard from a 2007 Apache airstrike in Baghdad in which two Reuters correspondents were reportedly killed. The Apache helicopter bore the call-sign “Crazy Horse 18” and inspired the title for this artwork. Audio and video transmissions from the airstrike , which had been released by Wikileaks in 2010 under the title “Collateral Murder,” were shocking due to the apparent indifference of the soldiers in regard to the loss of life, with one soldier saying, “Oh well. Well it’s their fault for bringing their kids to a battle.”
The work was installed on October 9, 2013 as part of Banksy’s highly-publicized New York City residency, “Better Out Than In,” a reference to a quote attributed to 19th century impressionist painter, Paul Cezanne, “…all pictures inside, in the studio, will never be as good as those painted outside.”
Accompanied by a custom-built display stand with an original paint-splattered traffic cone from the installation. Banksy’s Instagram post of this artwork from his personal account can be seen via link upon request.
