After a Guess clothing store in London allegedly deployed one of Banksy’s murals for a window display without permission, the anonymous British street artist has taken to social media to encourage shoplifters to visit the offending retailer and make full use of their five-finger discount in return.

“Attention all shoplifters,” reads an image that was posted to Banksy’s verified Instagram account on Friday morning. “Please go to GUESS on Regent Street. They’ve helped themselves to my artwork without asking, how can it be so wrong for you to do the same to their clothes?”

The image, which had already racked up hundreds of thousands of “likes” within its first hour online, was posted without an additional caption but does clearly show the in-store in question.

With the backdrop of a well-known Banksy piece of a masked Palestinian man about to throw a bouquet of flowers like a grenade, the Soho storefront appears to be promoting a new clothing line dubbed Guess x Brandalised. The Banksy piece is variously titled “The Flower Thrower,” “Rage” or “Love is in the Air,” which is

The “art-inspired” fall/winter clothing collection of shirts, jackets and accessories actually features a number of Banksy’s iconic murals, which are able to be used under Brandalised’s “urban graffiti license,” Guess said in a press release announcing the collaboration.

The clothing line has been available in the U.S. and online in Europe since late October, though it is unclear if or how Brandalised’s partnership with Guess will negatively impact its licensing agreement with the artist.

“The graffiti of Bansky [sic] has had a phenomenal influence that resonates throughout popular culture,” Paul Marciano, chief creative officer of Guess, said in the release. “This new capsule collection with Brandalised is a way for fashion to show its gratitude.”

'Copyright is for losers'

Many observers commenting on Banksy’s Instagram post, and on other social media sites such as Twitter, praised the artist’s shoplifting directive and suggested it was a justified tit-for-tat. Others stepped up to criticize him—not just for his encouragement of a crime, but for what they perceive as a hypocritical response to trademark infringement.

In his 2005 book “Wall and Piece,” for example, Banksy wrote that “copyright is for losers,” and he has historically even provided high-resolution images of his artwork on his website for the public to download. But European Union courts have often ruled against his efforts to preside over his own portfolio, citing Banksy’s concealed identity as antithetical to his assertions that his art is his alone to control.

Earlier this week, though, a board of appeal did offer the artist a boost, revalidating a trademark to one his most famous pieces amid a years-long dispute with greeting card company Full Colour Black, The Art Newspaper reported on Wednesday.

Guess has yet to publicly respond to Banksy’s post. Staff members at the company’s Regent Street store in London were unable to be reached for comment.
