As the list of exhibitions demonstrates he has achieved wide exposure and critical acclaim on two continents culminating in several singular honors. In 1976 he was awarded life member ship in the Society of French Artists, and in 1981 and 1991 he received special commissions to create first day covers for the World Federations of United Nations Associations. American Artist has published an extensive article about his work. He has published fifty graphic images in Paris and Mallorca. Zupan's muse is light.

He selects a subject rather objectively from the many possibilities that surround him. Once his materials are assembled, the day perfect, his mind clear, he becomes entranced in the act of capturing the subject with his brush strokes.
