Book excerpt: "In 1970, photography curator Peter C. Bunnell organized the exhibition Photography into Sculpture for the Museum of Modern Art in New York, bringing together twenty-three photographers and artists from across the United States as well as Vancouver, British Columbia, whose work challenged accepted practices and categories. The Photographic Object 1970 serves as an exhibition catalogue after the fact, an oral history, and critical reading of exhibitions and experimental photography during the 1960s and 70s. It proposes precedents for contemporary artists who continue to blur the boundaries between photography and other art mediums."--Provided by publisher.
