In August 1978, photographer Ethan Hoffman and his journalist friend, John McCoy, quit their paying jobs at the Walla Walla Union-Bulletin to do an in-depth study of the biggest story in town, the Washington State Penitentiary. The result of their work was the iconic book, Concrete Mama, Prison Profiles from Walla Walla. In this video, Ethan Hoffman talks about making Concrete Mama against a backdrop of images from the book.
