An acoustic guitar signed by 16 acts at last year’s Rewind raised £400 for charity.
The Helen and Douglas House shop in Duke Street, Henley, auctioned the instrument and the winning bid came from Richard Sargent, from Witney.
Shop manager Jean Hugill said: “Richard was determined to have the guitar. He told us to call him if any of his bids were bettered and he would submit a new one.”
Mr Sargent, who attended last year’s festival, said: “The guitar will take pride of place in my house. I’ve asked a carpenter friend of mine to make me a wooden case for it.”
