Regular visitors to Travel Between The Pages know that here at TBTP World HQ we are inordinately fond of silly re-imagined book cover art. There’s something about old pulp fiction paperbacks that calls for satirical reworking. Surprisingly, these clever fake book covers were created by a university professor of physics for the very clever website Skulls in the Stars. Take a look, but be prepared that some covers may be considered NSFW by some prudes.
