Creepy!
Cribbed from Hisham's post at The Great Curve: Creepy Magazine: Issues 1-40.
There's some really lovely stuff up here, by masters of comics and horror both: Frazetta, Davis, and Sutton all on the first page. Some of the work just screams 60s/70s, but a lot of it is timeless, and artists working on covers today would serve themselves well by taking a look.
