Remember when trading cards were a big thing? You would buy a folder filled with plastic inserts that you could place your cards in to show off to your friends. Baseball and Basketball cards were big hits. To cash in on the success of sports cards, things like Movies, Musicians, and even television shows showed up in the trading card industry.
I went to a local game store that had some leftover 1990's relics, I bought a few packs, and hoped for the big money.
