Josef Muller-Brockmann's graphics left a lasting mark on Swiss visual communication from the 1950s onward. His posters demonstrate how a sober, formally reduced language works best for conveying a universal, timeless message. Poster campaigns for long-time clients such as the Tonhalle concert hall in Zurich or the Automobile Club of Switzerland follow strict functional criteria and yet exhibit a variety of design solutions and exciting, dynamic compositions. This book presents selected posters by Muller-Brockmann and places them in the context of their own time while also examining the validity of his solutions from today's point of view. 100 illustrations
