A guitar played by George Harrison and John Lennon has fetched £294,000 ($570,000) at auction in New York.
Harrison used the guitar during the recording of the album Revolver
The Gibson SG guitar was used by Harrison from 1966 to 1969, including during the recording of Revolver, and by Lennon during White Album sessions.
Other lots in the Christie's auction included a letter by Kurt Cobain, which fetched almost £10,000 ($19,400), and a school book report by Britney Spears (£1,000).
The rock and entertainment memorabilia auction raised more than £1.1m ($2.13m) in total.
Hall of Fame
George Harrison had given the Gibson guitar to Peter Ham - of the rock band
Badfinger - in 1969.
George Harrison died of cancer in 2001
When Ham died in 1974, it was stored away by his brother and not rediscovered until the US Rock and Roll Hall of Fame contacted him in preparation for a Badfinger retrospective in 2002.
Since then the guitar has been on loan to the Hall of Fame, in Ohio.
It sold to an anonymous bidder on Friday.
Among 70 items of Beatles memorabilia on auction, there were also never-before-heard original tapes of an interview of Lennon by a reporter for the Washington Star newspaper from 1975.
These sold for £27,900 ($54,100).
The letter by Nirvana frontman Kurt Cobain, written in 1991 three years before his suicide, described to his then-wife Courtney Love hallucinations he experienced after taking LSD.
Three ringside photographs of Muhammad Ali and Joe Frazier from their 1971 fight, taken by Frank Sinatra, sold for a total of
around £7,500 ($14,500).
A Christie's spokesman said: "There was
interest across all sectors from early Hollywood all the way through to Britney
Spears' book report."
