Carter’s works had been labeled, surrealism, Magic Realism, geometric abstraction, pop and op, but no category could capture his style completely. It was in the mid-1960’s, in his series called “Mandalas,” that his fascination with the egg-shaped ovoid began. Author James A. Michener has commented that the egg in Carter’s works is “. . . a mysterious symbol evoking the past, the origins, the overtones of Christianity.” In addition, Carter has painted murals for a number of buildings. He also has taught, lectured and judged at such notable schools as The Minneapolis School of Art, Ohio. University, Lafayette College, Iowa State and his alma mater. On his works Carter has said: “for me no great art has ever existed without some mystery and some awe. It is that intangible which can never be defined but only felt in an elusive way that stirs the spirit.”
