New York: G.P. Putnam's Sons, (1967).
True first edition, the American preceded the British for this title. Spine gilt a bit tarnished, and the text block a little bumped, very good in very good dustwrapper with some overall toning and a crease on the front flap. Nicely Inscribed by the author. Fifth book featuring the involuntary agent known as Harry Palmer through his Michael Caine-portrayed screen incarnations.
