Guitars once owned by legendary music stars Jimi Hendrix and Prince are to be sold at an auction in London.
The Epiphone Acoustic that rock musician Hendrix played for three years - longer than any other guitar used in his career - is expected to fetch between £80,000 and £120,000 when it goes under the hammer at Bonhams this week.
Bass player Noel Redding once said he remembered Hendrix purchasing the instrument "second hand, for about 25 US dollars, in New York after our first tour of the States".
Hendrix gave the Epiphone to Blue Mink guitarist Alan Parker in 1970, the same year he died from an apparent drugs overdose, aged just 27.
The instrument went on to be used on recordings by acts including Dusty Springfield, Walker Brothers, Paul McCartney and David Bowie.
Prince's Cloud Guitar is estimated to fetch between £25,000 and £30,000.
The singer used the Cloud model throughout his career, and the instrument up for grabs at the auction was taken on the Act I and II, Prince and the New Power Generation Tours of 1993.
The vendor won the guitar in an MTV competition.
Prince died of an accidental overdose in April, aged 57.
The instruments will go under the hammer at Bonhams' Entertainment Memorabilia sale.
Other lots include an Imperial Bosendorfer concert grand piano played by Queen, Coldplay, Robbie Williams and Talk Talk, which is valued at around £20,000 to £30,000, and a silk jacket worn on stage by Rolling Stones star Keith Richards.
The single-breasted jacket, estimated at £10,000 to 15,000, can be seen in numerous photos of the band on and backstage at the Palladium in 1967.
Bonhams' Entertainment Memorabilia auction takes place at noon on December 15.
