"Flower Girl," a delicate stencil on a massive brick wall by popular street artist Banksy, is displayed in a warehouse in the greater Los Angeles area Wednesday, Dec. 4, 2013. The artist painted it on the side of a Los Angeles gas station in 2008. The building's owner carefully removed the wall section, which is 9 feet high, 8 feet wide and weighs nearly 5,000 pounds, framed it in sturdy aluminum and brought it to Julien's Auctions. Auctioneer Michael Doyle says the piece could fetch more than $300,000 at auction on Thursday, because, "Celebrities are Banksy-crazy."

(AP) - A Los Angeles gas station owner is selling a piece by one of the world's hottest graffiti artists. "Flower Girl," by the elusive street artist Banksy, is up for bid on Thursday at Julien's Auctions in Beverly Hills. Gas station owner Eytan Rosenberg says he didn't know who Banksy was when a friend of a friend asked if the British artist could paint on his wall. The work depicts a young girl with a basket of flowers and a security camera looming over her like a vulture. When Rosenberg sold his family gas station last year, he painstakingly removed the painting and installed it in a sturdy aluminum frame. Auctioneer Michael Doyle says the 9-by-8 foot piece could fetch more than $300,000 at auction.
