Ballantine/ Del Rey Books (first edition) July 1978. Cover by H. R. van Dongen, 246 pages. Condition is near-Fine: tight and almost square with flat spine; trace of overall wear.

To me it seems just a little dark for a book of this vintage - but you may not be able to do better for a first edition, given the quality of paper the publisher chose.
