I spend a substantial amount of time looking through the sci-fi publisher catalogues of Ace, Pyramid Books, Dell, Doubleday, Signet, Ballantine, etc for both books to read and interesting covers that fit into various themes for my Adventures in Science Fiction Cover Art posts (INDEX).
While perusing I’m occasionally baffled by covers that I’ve sworn I’ve seen on other books — and lo and behold, publishers sold art to different publishers, often lesser-known and unable to commission their own work (a few recycle art from 20 years earlier!). Or, the same publisher would simply re-use an image for a later publication. Often, the artist wouldn’t be credited for the later edition so tracking the duplicate art is dependent on the mechanisms of memory!
Sometimes they employ little tricks to make the cover look *different* — by, uhh, flipping the image (for see above, Jack Gaughn’s original cover art for Anderson’s Three Worlds to Conquer and below, recycled art for Gordon R. Dickson’s None But Man ).
Or, desaturating the color (Powers’ cover for The City at World‘s End and the later book, van Vogt’s Destination: Universe).
If you know of any reused cover art please let me know!
This is not meant to be a complete list — I have vague recollections of at least four other duplicate covers I’ve seen but, I don’t remember the titles of the later books).
