Who remembers the trading card boom of the early 90s? I'm sure quite a few of us got caught up in the whole thing while we were in school - I remember going bonkers over comic related cards, especially the Fleer Ultra X-Men and Spider-Man card series. I don't have many of those cards in the collection these days - but I have been building a healthy collection of GPK and other non-sports related cards over the past few years. Anybody else picking up wax packs from time to time? Would be cool to hear about some more obscure series from over the years - or even some new interesting sets on kickstarter etc.
