@ossobuco,
I remember a retro exhibit of some of his watercolors at the Philly ARt Musuem many years ago. His wc were really good and expressive just like his chgaracatures. He did a number iof wc's of the amusement piers and tourist areas of the Jersey Shore and he expresssed the shallowness and loneliness of the area in such a fashion that the tourist bureau guys were really upaset.
