In the late 1950s Clark became the first American artist credited with exhibiting a shaped canvas. Shaped by studies in Chicago and Paris, membership in the Brata Gallery cooperative, and global expeditions from Morocco to Nigeria to the Yucatan, Clark understood color as inextricably tied to place — changing unconsciously, series to series, in response to light and location.
