Well, most likely you wouldn't have had all 11 of these iconic posters on your wall simultaneously, but if you grew up in a certain era you probably either owned or saw one of the following posted somewhere, whether in your own bedroom, on the wall of a dorm room, in a "hip" teacher's classroom, etc. Here are the stories behind those iconic posters:
1. Hang in There, Baby
There were hundreds of variations of a dangling kitten hanging in there, but this black and white poster was the original. Sadly, there is not much information to be found as to who created it; the copyright info leads to nothing but dead ends. However, one thing we can probably be certain of, as Marge Simpson noted when she saw the copyright date of 1968, is that the kitty model for the poster is either long dead or a candidate for Guinness World Records.
