I was wondering if anyone else were familiar with these. I don't know whether they came in packets with a certain amount in them (like most trading cards), because I got them when I was four one Christmas from a collectables shop and they (well over 100) just came in a plastic box. They're from 1992 and at the back of each card it has a joke and a description of the picture on the other side. The pictures are of SSt characters at the zoo, the circus (the same pictures which you could find on some View-Master reels from the same year), with pets, counting things, etc etc. I know they're not very old, but I'd like to know if anyone else is aware of these and if they're easy to come across. Thanks!
