A guitar that John Lennon played on the recording of The Beatles song Paperback Writer is expected to fetch up to US$1m (€795,865) at auction.
Lennon gave his Gretsch 6120 guitar to his cousin, David Birch, in November 1967 - a year after the hit single was produced in April 1966 at London's Abbey Road studios as part of the sessions for the band's Revolver album.
Mr Birch was given the guitar when he visited his older cousin at his Kenwood home in Weybridge, Surrey, and he asked him if he had one that he no longer wanted as he was trying to form his own band with friends.
"I was just cheeky enough to ask John for one of his spare guitars," said David.
"I had my eye on a blue Fender Stratocaster that was lying in the studio but John suggested the Gretsch and gave it to me as we were talking."
The Gretsch was part of Lennon's collection of guitars kept in his music room at the top of the house.
After leaving the Grestsch factory in Brooklyn, New York, the guitar has had only two documented owners, Lennon and Mr Birch.
The instrument is one of the most significant of Lennon's guitars to come on to the market in the last 30 years, said auctioneers TracksAuction.com.
Paperback Writer, written by Paul McCartney and Lennon, was the A-side of their 11th single and went to number one in the UK and US charts.
The auction, which begins online on November 14 and concludes in London on the 26th, contains more than 100 lots of Beatles memorabilia.
