NEW YORK.- Andy Warhol´s signature silver wig sold for 10,800 dollars at a Christie´s auction last night. On sale were multi-colored shirts, a cowboy hat, roller blades and a pair of paint-splattered shoes which sold for £4,300. Other Warhol lots included a 1977 Polaroid of Muhammad Ali taken by the artist and signed by the boxing legend - it sold for $19,200 (£10,500), more than twice the pre-sale estimate. The items were among gifts that the Pop Art icon bestowed on his nephews when they visited their famous uncle from the late 1960s until his death in 1987.

The top items in the celebrity sale belonged to Marilyn Monroe. A black cocktail dress worn during filming of "The Misfits" sold for $66,000, while a full-length ermine coat worn by Monroe in 1957 sold for $50,400.
