Pay it again Sam!

Of all the auctions houses in all the world …  the piano from the classic 1942 Humphrey Bogart-Ingrid Bergman film Casablanca has been sold at auction for $602,500 (£370,000) – around half of what it was expected to fetch.

The blue-and-white upright (pictured above) on which Sam (Dooley Wilson) played it again - "it" being doomed lovers Rick and Ilsa's song As Time Goes By – had been tipped to bring in as much as $1.2 million in the sale at Sotheby's in New York. It was put up for sale by a Japanese collector who purchased it for $154,000 at a Sotheby's auction in 1988. 

A few days earlier, a rare poster for Fritz Lang's Metropolis (1927) sold for $1.2 million. The art deco image came bundled with other memorabilia, including the poster for King Kong (1933), The Invisible Man (1933) and the original oil painting of Elvis Presley used on the poster for Jailhouse Rock (1957).
