The Maltese Falcon statue from the iconic 1941 movie is going under the hammer for $1.5 million (£1 million). The jewel-encrusted antique bird, which Humphrey Bogart's private investigator character Sam Spade exposes as a fake in the film, has been hailed as one of the greatest movie props of all time and is expected to sell for a seven-figure sum. Memorabilia expert Catherine Williams tells Britain's Daily Express, "It's the greatest film prop ever, described by Sam Spade as 'the stuff dreams are made of.' The irony is this lead fake is now going for a fortune as the ultimate movie collectors' item." The statue is believed to be based on the Kniphausen Hawk, a ceremonial vessel made for George William von Kniphausen, Count of the Holy Roman Empire in 1697. The prop will go up for auction at Bonhams in New York on 25 November (13).
