Enter to the Realm of Satan!

Compare, if you will, the covers for these erotic occult novels from the late 1970s by Brian McNaughton. The first three are from Carlyle Books, easily  some of the dullest covers ever (by Ed Soyka, perhaps?); then you'll find the early '80s UK editions from Star Books. Oh, land of Aleister Crowley and Hammer Horror, we'd expect nothing less!
