LONDON (AFP) ― The auction of works by Banksy, the world’s most infamous graffiti artist, has angered residents of looted London neighborhoods and “embarrassed” the artist as the sale of street art becomes a lucrative enterprise.

Hollywood A-listers Angelina Jolie and Brad Pitt are fans of the British artist’s stencilled designs, known for their irreverent humour and political activism.

One of his most famous works is painted on the Israeli separation wall and depicts a young girl flying away while clasping a bunch of balloons.

Other notable designs by the Bristol-born artist include a demonstrator throwing a bouquet of flowers, instead of a rock, and a stencil of two British policemen wrapped in a passionate embrace.

The Sincura group, a VIP concierge company which promises to “acquire access to the inaccessible” sold a Banksy stencil in June.

“Slave Labour,” which depicts a kneeling child working away at a sewing machine making small British flags, appeared in 2012 on the side of a shop in the London district of Wood Green, the scene of serious disorder during the 2011 riots.

The mural was quietly removed and later sold at auction for more than 750,000 pounds ($1.2 million).

The sale enraged local residents, who said they felt “robbed.”

“We feel very strongly that this piece was given freely by Banksy to our area, it belongs to the community and it should be returned to Wood Green,” local councillor Alan Strickland told AFP.

At the end of July, a similar operation saw another painting disappear from Tottenham, another north London district which had been at the center of the 2011 riots.

The work “No Ball Games,” which shows two children preparing to throw a sign prohibiting ball games, will be “renovated” before being sold in 2014, according to the Sincura group.

A third sale, “Flower Girl,” is planned for Dec. 5 in Beverly Hills.

This stencil depicts a small girl with a basket in front of a huge plant in which the flower has been replaced by a surveillance camera with a rat’s tail, a recurring motif in Banksy’s work.

As with the other sales, proceeds from the painting, which originally appeared on the wall of a service station in Hollywood, will go to the building owner, not the artist.

For Richard Howard-Griffin, director of Street Art London, which organises guided graffiti tours of the British capital, these auctions bring to light the “naked profiteering and untrammelled capitalism which illustrates the greed inherent within human nature.”

The reclusive Banksy, whose real name is reported to be Robin Gunningham, did not respond to AFP requests for an interview, but his views on the subject are expressed in Oscar-nominated documentary “Exit through the Gift Shop.”

“So those famous auction houses have all of a sudden started selling street art, everything was a bit crazy, suddenly it all became about the money, but it never was about the money,” he said.

On his website (www.banksy.co.uk), Banksy invites people to freely download photos of his graffiti works and quotes Henri Matisse to convey his thoughts on the sales.

“I was very embarrassed when my canvases began to fetch high prices, I saw myself condemned to a future of painting nothing but masterpieces,” he writes.
