The works of Gianni Pettena, particularly those from the so-called ‘American’ period, and his many drawings whose visionariness was then often transformed into prophetic reality, have taken on a value that is by now considered historical, not so much for its specificity and uniqueness within the radical experimentation of the Sixties and Seventies, as for the influence it has exerted on the world of architecture, design and contemporary art. His work has been presented in museums and institutions such as the Venice Biennial, the Mori Museum in Tokyo, the PAC in Milan, the Barbican Centre in London, the Gamec in Bergamo, the Centre Pompidou in Paris and Metz, the Berlin Biennial, the Italian Pavillion at Expo 2010 in Shanghai, the Utah Museum of Contemporary Arts (UMOCA) in Salt Lake City, the Frac Lorraine in Metz, and the LACE (Los Angeles Exhibitions Center).
