Banksy makes another great point with this graffiti piece. Features the slogan “If graffiti changed anything it would be illegalâ€ï†? in a style which looks as though it has been dawbed on the shirt by the rat with his paw. As we all know, graffiti IS illegal; so we can assume that Banksy believes that graffiti in fact CAN change things if it carries the right message. 100% cotton Banksy tshirt. 10% of all royalties from our Banksy t-shirt range are donated to charity.
