Troels Marstrand, dit Mars 

Jac Mars (pseudonym of Troels Marstrand)

Dutch illustrator (1919-1992) realized in the first part of his career a certain number of covers, novels and magazines with "rose water" in the purest tradition of the American art of the 50s and 60s.

He subsequently tried painting in a surrealist vein in the movement of Salvador Dali.
