Banksy paintings on canvas bought during his 2013 'residency' in New York are to go under the hammer at Bonhams London. Purchased for just $60 apiece they will feature in their next sale of Contemporary Art on July 2nd for a price which reflects their true value.

Estimated at £50,000 – 70,000 and £30,000 - 50,000 Kids on Guns and Winnie the Pooh were both acquired from Banksy's Central Park stall where an unassuming trader sold his paintings to passing tourists.

Film footage shows Banksy's immediately recognizable black and white stenciled canvases stacked on a trestle table or suspended on the stall's makeshift metal framework. One canvas was stenciled with a discount store label announcing the price of each work as $60. The following day the event was documented on the artist's website: "Yesterday I set up a stall in the park selling 100% authentic original signed Banksy canvases. For $60 each."
