I find the idea of video posters really weird but to each their own.
Video rental stores back in the 80’s were often hip deep in them. And the turnover was so high, they would toss a bunch out every few weeks. As they usually were very similar to theatrical posters, it was a way to get a poster from your favorite movie. (If you were a regular customer, and asked nicely.) Some theaters were kind of stingy about giving away posters, claiming they were “studio property” and had to be sent back with the film. (The ones that were real dicks threw them out anyway.) I can’t imagine buying a real movie poster was that easy before Ebay, unless you lived near Hollywood, where memorabilia shops selling such items are common, or went to a convention.
I got a bunch of video posters to cover an ugly blank wall in the editing bay back in college. The room had all the charm of a cell block, and a video poster for the horror flick Prison was my idea of a joke. Was really pissed when someone decided to yank them down, and toss them without even asking me if I wanted them back.
