Bansky wall on sale for half a million

A painting by street artist Banksy has gone on sale in Miami in the US for a minimum of half a million dollars. The painting, called Slave Labour, was stenciled onto a wall in Wood Green last year. but earlier this month it was ripped out, and now it is being offered to bidders on an American art auction website.

Frederic Thut, who owns Miami Fine Art Auctions, says he is not looking for controversy - just for a good buyer.

It is still not known how the Banksy came to be for sale in America. It will be auctioned this weekend.
