Thank you for this link. With the exception of the piece I own, most of his work I've seen in passing or on a postcard advertising a show he was in. I understand he wasn't into computers, so he didn't have a lot of his work digitized. As the art world changed, he had to get more of his work in that format, but compared to his full body of work, only a very, very, small portion of it is available on-line.
