Pictures on Walls (POW) began life in 2003 as a collection of artists, graffiti writers, and illustrators who wanted to kick back against what they saw as the ‘centuries-old grip of the established art world’ that was making art both inaccessible and elitist. Who are POW, and what is a POW Certificate? The new COAs also include a rat running in the ‘wheel’ of a coffee cup ring, on the bottom left, and they’ll have a serial number at the top of the paper.

Street Art pieces made on walls, doors, etc., won’t get a certificate (with a few occasional exceptions). Pest Control only certifies pieces that were produced for commercial sale, mostly his editions of silkscreen prints. If you have a Banksy that’s not been verified as authentic, or are looking to buy one that doesn’t yet have a certificate, then Pest Control will answer any questions you have to determine whether he was responsible for the artwork, and issue a Pest Control Banksy certificate if this is the case. It was set up in 2008 and is run by Banksy himself as a not-for-profit handling service and point of sale for new works, to help authenticate genuine Banksy works and expose any forgeries, to help make sure people don’t fall foul of fraudsters. Pest Control is the only official body that can authenticate any Banksy print.
