Hang your wall on the Banksy art Flower Girl (2008), by Banksy. BUILDING a house and looking for that one unique, defining feature? A petrol station in Hollywood has just the thing. Admittedly, your new house should not be too far from Hollywood, as transporting this feature will be a challenge. But the effort will be worth it, and the investment might even pay dividends. The item in question is a plain white brick wall on which famous English graffiti artist Banksy has painted a girl with a basket being monitored by a CCTV camera atop a flower stem. The camera has a rat's tail, a recurring motif in Banksy's art. Flower Girl, painted in 2008, measures 2.7m by 2.4m. It will be sold at auction on December 5 by Julien's auction house in Beverly Hills. Julien's released a statement describing the sale as a "rare opportunity to own one of Banksy's early large-scale graffiti murals," adding that this was the first time a work of public street art by Banksy has been offered at auction in America. Another Banksy graffiti, Slave Labour, was offered at auction in Miami but was withdrawn at the last minute after a controversy arose over pulling down the wall in London on which it was painted. The graffiti was finally sold privately in June for more than $US1.1 million ($1.21 million) by the owner of the wall where the mural was discovered. Banksy, who strenuously conceals his true identity, is from Bristol in southwestern England. His work mixes humour and subversiveness: his artwork appeared on the walls of New Orleans after Hurricane Katrina and on a wall in the West Bank separating Israelis and Palestinians. However, not everyone is convinced by Banksy's genius. Guardian columnist Charlie Brooker said in 2006 that "Banksy's vague, pseudo-subversive preaching is often accompanied by a downright embarrassing hardnut swagger" and that his work is "dazzlingly clever to idiots."
