'Missing' Banksy Jubilee work listed for auction at £450,000

A Banksy painting has been put up for sale on an American auction website, after it was removed from the side of a Poundland shop in Wood Green, north London, last week.

The work appeared last May, and is thought to have been created by the controversial street artist Banksy. Known as Slave Labour (Bunting Boy), the piece shows a young boy hunched over a sewing machine making Union Jack bunting, and has been interpreted as a reaction to the Queen's Diamond Jubilee, the riots of August 2011 and the London Olympics.
