This exhibition presents architectural achievements on the fringe of established codes. It shows the marginal architectural construction in the United States in its most diverse aspects. We find hippie architecture from the counterculture of the 1960s, creations from a subculture. These popular and individual expressions are created not by architects and intellectuals, but by amateurs and common people. Documentary panel of the exhibition with photographs and drawings of atypical architectures throughout the United States of America. Photographic report. Exhibition at the American Center in Paris, then at the Musée des arts décoratifs, Centre de création industrielle, November 18, 1975 - January 12, 1976.
