Sarah Greenough, senior curator and head, department of photographs, National Gallery of Art, and Matthew S. Witkovsky, exhibition guest curator. Featured are some 50 Prototypes—on view together for the first time—and the mural-sized 12-panel color work Ronde de Nuit. Greenough and Witkovsky discuss the artist's interest in the postwar American landscape, as revealed in Prototypes, and his continuing preoccupation with industrially manufactured environments and how they are used to control contemporary society, as shown in Ronde de Nuit.
