I used to love these Presto Magix playsets.

Hours of fun spent using a pencil to rub off the dry transfer onto comic book-like backgrounds. I remembe having a superhero set, an underwater scene and I think I might remember a couple of Star Wars ones. In fact, I managed to find a link to someone else’s blog where they [url=http://seventyseveneightytwo.blogspot.com/2006/01/presto-magix-undersea-world.html]actually have a photo of the underwater one[/url] that I remember.
