A mosaic of Jimi Hendrix made from more than 5,000 different coloured Fender guitar plectrums is to be auctioned later.
The portrait, created by Manchester artist Ed Chapman, will be unveiled at a charity event at London's Abbey Road Studios.
The 39-year-old said the 120cm x 100cm work took him several days to complete.
"Jimi Hendrix is a guitar maestro and nobody played a Fender guitar like him," Chapman said.
"I decided to use plectrums to create a portrait of him because I like experimenting with different materials and textures and I think it is a fitting tribute to the musician.
"There's no better place for it to go on sale than at a legendary home of music and I hope it raises as much as possible for charity."
Money raised from the sale of the mosaic - which is expected to fetch up to £16,000 - will go to Cancer Research UK.
Chapman has previously created tile mosaics of footballers Eric Cantona and George Best and portraits of Manchester United manager Sir Alex Ferguson and Fulham boss Mark Hughes using coins.
