Ralph Steadman (born Wallasey, May 15, 1936) is a British cartoonist, renowned for his political and social caricatures and cartoons. Steadman had a long partnership with the American Gonzo journalist Hunter S. Thompson, drawing pictures for several of his articles and books. Much of Steadman's artwork revolves around Raoul Duke-style caricatures of Thompson: bucket hats, cigarette holder and aviator sunglasses.
