The doll's head in a circle, carefully drawn hands at the piano, and eyes closed in repose reminded me of a favorite cover for a book I have been unable to find cheaply, the intriguingly titled A Feast of Eggshells. Somewhere in my searches I discovered another similar cover and noted that signature, then began to track down more by Heindel. Which is how I discovered that he's a world-famous painter of ballet and other dance, whose artwork has been collected by Princess Diana, Andrew Lloyd Weber, and George Lucas! Claaaaasssy for a guy whose earliest works appeared on these "easy-to-see large-type" Gothic/occult paperback originals. I love it!
I could find only these four other horror covers, Suffer a Witch, Along Came a Spider, The Ouija Board and The Devil Boy. Personally, I think these are simply wonderful, as they feature all the signifiers of genre works of the era: creepy kids, eerie witches, haunted houses, Rosemary's Baby. If anyone knows of other covers he did like this, please let me know...
More interesting is that I've been seeing his work on more famous paperbacks for decades and didn't even realize it: his most well-known cover illustrations are for Signet's series of Ayn Rand reprints. Crazy, right? You can even buy the originals of these here.
