Do you remember when new movies on VHS videotape cost about $80 or more? In case you don't, I can assure you it's true; when video stores were just beginning, very few people bought VHS movies for home use, they rented them. Thus, the store owner ponied up the expensive price and then made his money renting the tapes out.
During that time in the early 80's I was pals with a guy that worked at one such store and he got me all kinds of promotional materials when they were done with them, or if they never used them. Here is a scan of the promo slick for the new release "Jason Lives." It's my favorite of all of the Fri the 13th sequels, and all this week I'm watching the movies in order leading up to the new remake release on the 13th.
Of particular interest to me are the tips and suggestions to help promote the movie. You wouldn't see that type of thing done very much in stores nowadays. If a family walked into a video store now with the kids, and saw the employees dressed like Jason's victims with fake machetes and bloody clothes, they'd scream and run out, covering the kid's eyes on the way.
