A guitar played by John Lennon and George Harrison has sold for $408,000 (£269,000) at auction.
The custom-made instrument (pictured), made by the VOX company in 1966, was bought by an anonymous US buyer in New York.
Harrison played the guitar while practicing I am the Walrus during The Magical Mystery Tour, and Lennon played it while recording a video session for Hello, Goodbye.
Julien's Auctions said the guitar had exceeded its estimated value of $200,000-$300,000 (£132,000-£198,000).
"It's extraordinary when you have the opportunity to offer such an amazing piece of music history as the VOX guitar played by both George Harrison and John Lennon," said Martin Nolan, Executive Director of Julien's Auctions.
"From Here Comes the Sun to Hello Goodbye, this guitar is truly one of the most historical pieces of music memorabilia Julien's Auctions has ever had the pleasure of offering."
After playing the guitar, Lennon gave it as a 25th birthday present to Alexis "Magic Alex" Mardas in 1967, a member of The Beatles' inner circle during the sixties.
Beatles memorabilia is incredibly popular and continues to command high prices at auction, despite the group separating more than 40 years ago.
In April, a signed copy of The Beatles' 1967 record Sgt. Pepper's Lonely Hearts Club Band sold for $290,500 (£191,200) at a Texas auction.
In 2009, George Michael paid $2.1 million (£1.4 million) for the Steinway Model Z piano Lennon wrote Imagine on, while Lennon's handwritten lyrics for All You Need is Love fetched $1 million (£658,000) at auction.
In 2008 the painted drum skin featured on the cover of Sgt. Pepper's Lonely Hearts Club Band sold for $1.7 million (£1.1million) at Christie's in London. At the same sale, a pair of tinted prescription sunglasses belonging to Lennon, which the singer wore for the cover of the single Mind Games, raised $78,400 (£52,000).
