(New York: Lustrum, 1971).
Second edition, and the first hardcover edition. Quarto. Fine in a slightly rubbed, very near fine dustwrapper. Clark's first book, a cult classic among photography collectors. Maybe the only unsigned copy we've seen. The first edition is cited in Parr and Badger, The Photobook Volume 1, p. 260; Hasselblad, The Open Book, p. 272-273; Roth, The Book of 101 Books, p. 208-209.
