A collection of works by graffiti artist Banksy have sold for more than £400,000 at an auction in London.
Girl and Balloon, one of 18 pieces sold on Thursday, fetched £73,250, almost five times its estimated pre-sale price.
The image has been painted directly onto the cardboard backing of an Ikea frame.
The stencil painting Leopard and Barcode, which has never been under the hammer before, sold for £75,650.
The Urban Art sale took place at Bonhams auction house.
In a separate sale at the auction house, a screen print of a dollar sign by American pop artist Andy Warhol sold for £44,450.
Initially painted onto a handkerchief and given to friends in 1981, the picture has since been mounted onto board.
The sale appears to contradict claims, earlier this week, by art critic and former curator Julian Spalding - who predicted the bottom would soon fall out of the contemporary art market and conceptual work by high profile artists would become "worthless".
