Sandberg letterhead (Letter to Becky Reis)

Willem Jacob Henri Berend Sandberg was a Dutch designer, typographer, and curator whose work spanned graphic design, exhibition design, and art direction across six decades. He served as director of the Stedelijk Museum Amsterdam from 1945 to 1962, where he shaped the institution's visual identity and experimental approach to modern art presentation. Sandberg's graphic work was characterized by bold typography, playful use of negative space, and an integration of Dutch modernist principles with postwar artistic innovation. His influence extended across European design culture through his publications, posters, and curatorial vision.
