War Child is always teaming up with A-list musicians and artists to help raise funds for children in need. This time around, they’ve tapped famed British artist Damien Hirst to hand paint a Carparelli guitar with his trademark “spin painting” technique. The one-of-a-kind signed guitar will be auctioned off at Christie’s London on February 17, with all profits going towards War Child’s humanitarian efforts. –Kayla Chobotiuk
