The Prototypes part consists of images from Baltz' portfolio made from 1967 through the early 1970s that shows images of the sides of warehouse sheds, stucco walls, empty billboards, and other geometric forms found in the postwar suburban landscape.
According to the National Gallery website, this work deals with "the fascinating and disturbing transformation of the American landscape into an unending terrain of anonymous commercial architecture."
The Ronde de Nuit part consists of work made from 1991-1992, a 12-panel depiction of surveillance sites and the people who work in them made with surveillance cameras. The title echoes Rembrandt's Night Watch, and, again according to the National Gallery, "reveals the artist's continuing preoccupation with industrially manufactured environments and how they are used to control contemporary society."
