Back in the Golden Age of the Atari 2600 Activision had a high score club. A lot of their games were eligible. You would send them a photo of your high score in a game and they would send you a patch to sew onto your nifty jean jacket, or maybe you had one of those Michael Jackson jackets with all the zippers, (this was the early to mid 80's after all). Where ever you put it the Activision patch meant that you were a video game master.
Known Activision Patches, (and what you had to do to get them).
