A custom-made guitar used by both John Lennon and his Beatles' bandmate George Harrison has been given a rare public outing ahead of its auction for upwards of £130,000.
The Vox guitar, with an unusually shaped wood-finished body, was made in 1966 and given by Lennon to a pal of the band, known as Magic Alex.
It is on public display in London until Saturday, when it will be sent off to New York where it is being sold by Julien's Auctions on May 18.
The instrument is said to be one of only a few known to have been played by both guitarists.
A plaque on the reverse says: "To Magic Alex, Alexi thank you for been a friend."
It is being exhibited at the Stafford London hotel in St James's, London.
