"This book ... [shows] how the artist worked out his developing ideas primarily through drawing. Included are examples of work from his early years, such as the preparatory drawings he made as a muralist for the WPA in the 1930s, in addition to the increasingly abstract work of the 1940s and 1950s, and the sequence of pictorial experiments that led to his reintroduction of the figure in the late 1960s. Also reproduced, in color, are a number of painterly gouaches and a series of acrylics"--Back cover.
