Nevelson's celebrated wall assemblages date from the late-1950s. In her exhibitions these became total environments which enveloped the viewer. The elements of each work were potentially variable, since they were made up of the same basic grammar of boxed wooden units. Units from one wall could be dismantled and incorporated into another, which is the reason for the seven-year date span of this work, finished in 1964 but incorporating parts dating back to the 1950s. Most of Nevelson's works were painted black but there are others in white and gold. Her assemblages reflect the experience of city life in New York.
