New York: Community Press, 1965. First Edition. Quarto. Heath's first and only major monograph, rescued from the scrap heap of obscurity by Michael Torosian's brilliant reissue in 2000. Prior to the resurrection, Dialogue was probably the greatest unknown American photobook, and Heath, while revered amongst photographers for his emotional and technical brilliance, had yet to become widely collected. The bridge in American photography between Robert Frank and Larry Clark, and one of the most gripping American photobooks ever published. (Parr / Badger, v2, 104; Auer 444). Fine in a near fine jacket with a small sticker over the printed price, a few tiny edge nicks, and minimal loss at the bottom flap folds.
