Authenticity & Provenance

At Prescription Art, trust is the foundation of everything we do. We have been sourcing and selling authentic works — including Banksy originals and authorised editions — since 2004. Every piece we offer comes with documented provenance and our personal guarantee of authenticity.

Pest Control Authentication

Banksy's official authentication body, Pest Control, is the only authorised source for authenticating original Banksy works. All Banksy originals and signed works sold through Prescription Art are authenticated by Pest Control. We provide buyers with the accompanying Certificate of Authenticity issued directly by Pest Control, giving you complete confidence in your purchase.

Lazarides Letters of Authentication

For select works — including the celebrated Banksy Di-Faced Tenner — we hold signed and fingerprinted letters of authentication from Lazarides, Banksy's former gallery and one of the most respected names in the street art world. These letters provide an additional, independently verifiable layer of provenance directly linked to the original publisher.

Twenty Years of Expertise

Prescription Art has been at the forefront of the Banksy market since 2004 — before most galleries had taken notice. This two-decade track record means we have built direct relationships with artists, publishers, and estates, giving us access to works of verified origin that many dealers simply cannot offer.

Our expertise has been recognised in the press, including coverage in The Observer, and we are regularly consulted by collectors, institutions, and fellow professionals on questions of authenticity and valuation.

Our Guarantee to You

Every work sold through Prescription Art is guaranteed authentic. If you ever have any doubt about a piece you have purchased from us, we will work with you directly to resolve it — no questions asked. We stake our reputation, built over more than twenty years, on the integrity of every single sale.

If you have questions about provenance or authentication on a specific work, please get in touch — we are always happy to share full documentation before you buy.
