This is an undated image of an art work from British artist Banksy made available by Haringey Council Wednesday Feb. 20, 2013. The stencil by the famed, secretive graffiti artist of a young boy sewing Union Jack bunting on an antique sewing machine appeared on the side of a north London bargain store last May. Soon the gritty Turnpike Lane area was drawing art lovers keen to see Banksy's typically cheeky take on the Diamond Jubilee celebrations of Queen Elizabeth II's 60 years on the British throne. Last week it vanished, leaving nothing but a rectangle of exposed brick — only to reappear on the website of a Miami auction house. Listed as "Slave Labor (Bunting Boy)," it is due to be sold Saturday with an estimated price of between $500,000 and $700,000. (AP Photo/Haringey Council) NO ARCHIVE
