A guitar owned by George Harrison is heading to auction in the US along with other Beatles and rock memorabilia.
The Julien's Auctions sale takes place on May 17 at the Hard Rock Cafe in Manhattan. The 1962 Rickenbacker 425 is estimated to bring up to 600,000 US dollars (£355,000).
Harrison bought the guitar in 1963 at Fenton's Music store in Mount Vernon, Illinois. He had gone there to visit his sister.
He had the guitar refinished from a Fireglo red to black to match John Lennon's Rickenbacker.
The auction also has a Beatles '65 album signed by the Fab Four. It could bring up to 300,000 dollars (£177,500). The auction house said any albums signed after Beatlemania began in 1964 are extremely rare.
Other highlights include Jimi Hendrix's Sears Silvertone electric guitar. Its presale estimate is up to 100,000 dollars (£60,000).
