Over his four-decade-long career, Dunham has developed his unique pictorial language. His formal vocabulary initially took the form of quasi-psychedelic biomorphic abstractions and has since evolved to include well-defined concrete figures—such as women, men, and suns—that possess the clarity of images found in coloring books. Dunham has masterfully constructed a graphic world of “nameable things” like trees, flowers, houses, and guns, deliberately avoiding subtlety and striving to distill a subject to its essential visual archetype.
