A collaboration between the Museu de Arte Contemporânea da Universidade de São Paulo (MAC-USP), and the Terra Foundation for American Art, the exhibition explores the influence of artist and printmaker Stanley William Hayter (19011988) on the evolution of printmaking in the United States and Brazil during the first half of the 20th century. Assembled around a never-before exhibited group of prints gifted in 1951 to MAC-USP by American philanthropist Nelson Rockefeller (19081979) and another smaller group gifted by Lessing Roswenwald, the exhibition highlights the impact that Hayter, well known as an experimental printmaker and teacher, had on a vast group of established and emerging artists. Centered on key prints by Hayter, the works made by Atelier 17 go far beyond the borders of the United States of America and Europe, with echoes on the production of Brazilian artists at the time, such as Geraldo de Barros and Lívio Abramo (these names having large presence in the MAC USP collection). The exhibition has its origins in the research by Carolina Rossetti de Toledo for her Master thesis on the Nelson Rockefeller (1908-1979) donations to encourage the creation of modern art museums in Brazil. The research has found that the engravings now gathered in the MAC USP collection here exhibited were donated to the Museum of Modern Art of São Paulo (MAM) by Rockefeller in 1951.
