This Fender Strat is autographed by Ronnie Wood of the Rolling Stones. Shot in the window of an art gallery in London on my iphone. Its priced around 2 grand if I remember correctly. Not sure I would call it art though. As well as a guitarist, Ronnie is a spectacular painter specialising in portraits and Horses. If you have an interest in art you should check out his work online.
I once met him in Dublin as he was out shopping with his then wife Jo, as a fan it was a great experience. He is so down to earth, not what you might expect.
