Man, who didn't love Presto Magix? If you don't recall the brand name, you may have called them "rub-on transfers" or something generic like that.
Actually, Matt from X-Entertainment points out that Presto Magix had its own stick thing that you were supposed to use for rubbing, but we always, always used a sharp pencil.
They came in all varieties, like Shrinky Dinks or coloring books. Scooby Doo, superheroes, Strawberry Shortcake, Star Wars...if you could name it, they probably had it.
Matt points out you could also get quite creative. He notes: "The kit gives you the chance to create scenes you'd never see in the movies. Up above, father and son mutilate the Rancor Monster with their lightsabers. You know, that's a much more touching moment than what we actually got. Vader and Luke fighting dinosaurs side-by-side is way more heartfelt than Luke crying while burning his dad's dead body to a crisp. Then again, I'm not so sure anyone would really be surprised by the idea that a Presto Magix canvas scene can make more sense than a Star Wars movie script."
Do not confuse them with this Presto Magic Show from the 70s, which apparently was a magician's kid for dorky kids, judging by the kids in the commercial.
Ringing any memory bells? Do you remember any particular themes? Did you use a pencil or the provided stick thing? Also, here's a video of some guy showing off his 1980s Presto Magix pages.
