Stephen Gammell’s illustrations from Scary Stories to Tell in the Dark.
I just bought a copy of this the other night at a used bookstore for 2 bucks. When I got back in the car, my fiancee didn’t even get through half of “What did you buy?” before she literally jumped in her seat at the sight of the cover.
"I read that book when I was a kid!" she said. "There was this picture of a FREAKY old woman in there that gave me nightmares, but I couldn’t stop checking it out of the school library anyway."
