The cover on the left is the 1973 first printing by Avon Books. The one on the right is from the same year but is the sixth printing. I think I prefer the one on the right. I purchased the one on the right at a Half Price Books in Austin (probably the one on Lamar) and I found the one on the left on my Dad’s bookshelf. “The Lathe of Heaven” is LeGuin’s tribute to Philip K. Dick. It’s been made into several movies, some of which I’ve seen.
