I was about 8 or 9 when I ripped into one of these for the first time ever, and so ensued a 35+ year obsession with them and the sport(s)....

The Team Stickers have 2 possible backs:
1983 Season Totals
1983 Home & Away Totals
Except some Team Sticker "variations" have backs that vary.

This was also the first set I collected as a kid (along with Topps), getting packs at the supermarket and 7-11. My first trip to a card store to fill more of the set didn't come until 1991, and I finally finished the base set in the mid-90s (and completed the stickers last summer), but the Update set was way too expensive for me at the time. I finally got my hands on one (with a graded Clemens) for a decent price in 2004 and it was an amazing feeling.
