A rare guitar played by Beatles pair John Lennon and George Harrison worth about £150,000 will go on display in London this week.
The Beatles VOX guitar, a custom prototype made in 1966 and later given to "Magic Alex" Mardas, a friend of the band, will be unveiled at The Stafford London hotel in St. James's Palace.
After going on display from Thursday to Saturday it will be taken to New York for auction.
The guitar, one of a few known to exist that was played by both Lennon and Harrison, will be sold at Julien's Auctions on May 1.

Unseen photos of The Beatles are to go up for sale after lying in a family album for nearly 50 years.
The 20 black-and-white snaps have never been published and give a rare behind-the-scenes glimpse of the Fab Four on the cusp of becoming a world phenomena. They were taken as the band filmed their first movie, A Hard Day's Night in March 1964 at the Scala Theatre in London.
The photos show the band with their instruments but also between takes in off-guarded moments, with one picture of Ringo Starr resting on bricks to boost his height for the cameras.
