Ballantine Books, 1975. Ninth printing of this, the first paperback edition which was first printed in 1969.
Very good. Very mild shelf wear around the edges with spine ends and fore corners faintly bumped/worn. Subtle line of wear across fore edge of text block with bump to that area of front cover. Small closed tear to bottom edge of front cover near spine. Binding is tight, spine is straight and without reading creases, and all pages are clean and unmarked though tanned.
