Exclusive autographed items from Coldplay, Elbow and Pet Shop Boys are up for grabs as part of Mencap's Little Noise Sessions charity auction.
A selection of memorabilia is online on eBay, with all proceeds going straight to Mencap, a learning disability charity.
The full list of artists who have contributed to the auction includes Ed Sheeran, Example, Paolo Nutini, The Killers, Lostprophets and Marina & The Diamonds.
As well as signed vinyl records and t-shirts, there's a keyboard used by Elbow and a guitar from Coldplay.
Mencap's Little Noise Sessions are a series of acoustic sessions organised to raise money for the charity - and you can also bid to win a pair of tickets to every Little Noise Sessions gig organised in 2012.
