Neues Bauen (New Building) (Poster for Deutsche Werkbund Exhibition at the Kunstgewerbe Museum, Zürich)

Theo H. Ballmer was a Swiss graphic designer and typographer active in the mid-twentieth century. Working primarily in printed media, he developed compositions that synthesized Swiss modernist principles with functional design logic. His practice engaged typography, layout systems, and geometric abstraction as tools for visual communication. Ballmer's work contributed to the visual language of postwar Swiss design culture.
