All my life I've had fond memories of the Give-A-Show projector set that I had as a very small child. I would cry and beg until my dad would put on the projector and supply his own crazy narration to go along with the pictures. We had slideshows for Scooby-Do, the Flintstones, Yogi Bear, and other classic cartoons. Each slideshow was only a few panels long, so my poor dad must have been thoroughly sick of them by the time I outgrew the damn thing.
I remember in particular the Peppermint Phantom from one of the Scooby-Do slideshows, which I found absolutely terrifying. I remember that it reminded me of scary nightmares I'd had while sick with a high fever. The bizarre stripe pattern was disorienting, as was the lack of a proper head and total absence of a mouth. The fingertips, red and poised to strike, looked like they'd been dipped in blood. I tell you, finding the above picture was a freaky experience; I hadn't remembered the Peppermint Phantom in probably 25 years, but the second I saw it, I got this powerful feeling of dread...
Apparently I'm not the only one for whom these slideshows are a lasting memory. In fact, there's an entire website devoted to them. I lost several hours on this site, so beware!
