Canadian guitar-maker Carparelli is to auction a series of 10 guitars, each painted by well known artists, to raise money for 10 charities. The first is by Brit Art pioneer Damien Hirst, which will be auctioned later this year by Christies for the Warchild charity.

Check out Hirst's guitar below. It's expected to be sold for £50,000-70,000.

A second guitar has been painted by American artist Jim Warren, and is being signed by musicians including Mike Love and Bruce Johnston from the Beach Boys and Kris Kristofferson. It will raise funds for Amnesty International.
