Roy Lichtenstein pop art sells for $45m

A work by Roy Lichtenstein has sold at auction for nearly $45m, a new record for the US Pop Art icon.

Sleeping Girl, from 1964, went for $44.9m (£27.8m) at Sotheby's New York sale of post-war and contemporary art.

The same sale saw Andy Warhol's Double Elvis, a life-sized silver silkscreen image of Elvis Presley depicted as a cowboy, fetch $37m (£23m).

The sale saw the hammer drop at $40m (£24.8m) for Sleeping Girl and $33m (£20.4) for Warhol's Double Elvis, before buyer's premium.
