According to a post at The Magic Robot, Milton Bradley released three puzzles featuring art from Creepy covers, and three featuring art from sister magazine Eerie. I’ve seen a couple on eBay and both had a copyright date of 1977. I’m not a collector, but I might make an exception for these. It’s a brilliant idea, and I find it telling that a major, family friendly corporation like Milton Bradley would license the lurid output of Warren Publishing.
You can read Creepy #28 at the Internet Archive. The cover artist is Vic Prezio, who contributed to Eerie and Famous Monsters of Filmland as well. He also worked extensively in the men’s action-adventure pulps of the 1960s. See more of his work at Flickr.
Many of the original Warren titles are online now. If you’re interested in reviewing issues, drop me a line. I think that would be a fun, worthwhile project.

I’ll only go read it if you can promise me it reveals what the “only one thing left to do” is. The suspense is killing me.
JUMP ON THE UGLY BASTARD’S BACK AND CLIMB UP ITS EXPOSED RIBCAGE AND PULL ITS HEART OUT WITH YOUR BARE HANDS AND EAT THE HEART FOR BREAKFAST. Obviously.
