New York: Harper & Row, 1970. First Edition. Large quarto. SIGNED by Duncan and inscribed over two pages: "For Kay - / Just flashbacks / to / Bob's world / and / fractionally mine / but / not yours / Thank God- / David" and dated to the pasted end paper, "10 May 1986 New York". Special edition of this underrated monograph on the Vietnam War, with "Private Edition of the Author" indicated on the half-title page. Duncan photographed in Hanoi and on the front lines of three combat operations, which give his book its sections. Replete with stark images of combat and camaraderie, made possible by Duncan's immersion in the conflict. Near fine in an about very good price-clipped dust jacket showing water stains to the bottom panel of the verso and some small tears to head of spine.
