Here's a cool item I recently bought from a nice Ebay seller. These are ad slicks, which are/were glossy pages used to reproduce art for newspaper ads, and in some places are still used today. All of these are dated 1976, and are for a children's matinee series from American International Pictures. Full-size, the sheets are 11 1/2 x 14 1/2 inches, and have four ads to a page. They were a bit tricky to scan, but I got the job done. The films I bought ad slicks for are GODZILLA VS. THE THING, GODZILLA VS. THE SMOG MONSTER, YOG: MONSTER FROM SPACE (not Godzilla, but another Toho classic), and my personal favorite film of all time, DESTROY ALL MONSTERS. I think it's interesting how they changed the art around for the different sizes, and even changed the text to keep it interesting. If you want to download full-size scans of all 16 ads, a link is provided below.
