Richard Paul Lohse. Poètes à l' écart / Carola Giedion-Welcker. Bern: Benteli, 1946
“The cover design and typography by Swiss painter and graphic designer Richard Paul Lohse (1902-1988) is stunning. With its rectangular color fields in red, yellow, black and white, the cover reflects Lohse's "constructive" painting style he started to develop in the mid-1940s. The book was originally issued with a glassine protective dust wrapper. Set entirely in sans-serif, this small paperback is an early example of Swiss typography as it became internationally renowned in later years. The square format and the multilingual text are also typically "Swiss".”
