Bud Shark opened Shark's Lithography in Boulder back in 1976. Twenty-some years later, he moved to Lyons, changed the name to Shark's Ink and has been there ever since. Shark is a master printer who has worked with many internationally known artists, some of them over and over again. In putting together this stunning show, outgoing curator Cydney Payton chose works that expressed those long-term relationships. On view are pieces by Betty Woodman, Enrique Chagoya, Don Ed Hardy and Bernard Cohen. Of particular interest are the three-dimensional works by Red Grooms, in which the prints are cut up to make sculptures.
