A series of lithographs by Spanish surrealist Salvador Dali have sparked an auction battle after being discovered after 50 years spent in a London garage. The 11 prints were bought in the 1970s at a gallery closing down sale for just 500 pounds, before being auctioned by Hansons, with each piece exceeding its guide price of 500-700 pounds. One sold at nearly 5,000 pounds. "It's quite an exciting thing," says Chris Kirkham, Associate Director and Senior Valuer at Hansons Auctioneers Richmond. IMAGES AND SOUNDBITES
