First edition, Ace Paperback. Cover art by Leo Dillon and Diane Dillon. A strong thread of cover illustrations show dual image. Here, it could be two people -- Genly Ai and Estraven -- or the dual nature of the Gethenians.
An early hardback cover, prefiguring much of the cover art of the late 20th and early 21st centuries with its emphasis on a minimalist blue and white landscape.
