I mean, yeah, of course there is, as we live in the age where our memories of the past are preserved for us in the cloud, so it isn’t a surprise. But I’d forgotten these things even existed until they popped up in my Tumblr feed.
“Dedicated to the appreciation and preservation of the most important art form of the latter half of the 20th century: PrestoMagix,” the Tumblr in question has all sorts of package shots of various PrestoMagix “games” from the late 1970s and early 1980s, including several Marvel and DC Comics ones. If you aren’t familiar with the magic (excuse me, magix) behind these things, basically they consisted of an illustrated background and an acetate sheet of various characters, vehicles, etc. The idea was that you put the sheet on the background and rubbed the back with a pencil, so the image on the sheet transferred to the background — thus creating your own little story.
