DC was known for always pumping up sales of their superhero comics by putting a gorilla on the cover (hence Grodd, Titano, etc.).
For their supernatural (very light) horror books, it was skeletons, skeletons, skeletons. You’re getting no complaints from me. Just from Ghosts–this is the very first cover of that book–I could do a month’s worth of posts and I might do a couple of weeks, anyway.
