Wow, almost forgot about these. Girls had Fashion Plates or some other such nonsense, but we guys had Mighty Men and Monster Maker set (from Tomy, who also brought us great stuff like Strolling Bowling). You could use the plates, along with a pencil and paper, to create all sorts of cool rubbings. It was particularly useful for guys who couldn’t draw (or were too lazy to). The sound of those plates clanking into the slots, the snap of the holder as it came down on the paper, the feel of the charcoal pencil clacking over the plate ridges, the various Mighty Men and Monsters in their various poses. “Very nice!” the vampire on the TV commercial said. Very nice, indeed.
