The masterworks of one of the most influential teacher-artists of the twentieth century, originally published as a limited, boxed edition in 1963, was conceived as a guide and teaching aid for artists, instructors, and students. A paperbound edition, containing the unabridged text of the original edition, plus ten representative color plates, chosen from the original silk-screen reproductions and printed by offset lithography, was published in 1971. Since those color plates have now been worn out in repeated reprintings, Mr. Albers has selected ten different color studies, with new comments, for this revised edition.
