I think Ken Griffey Jr. will always be my favorite baseball player. Brings back memories of when I was a youngin and going to baseball card shows with my Pops. Upper Deck, 1989, Card #1 - Ken Griffey Jr.'s rookie card. Upper Deck sure picked a winner to kick off the set for their inaugural year in the sport card industry. I'm not sure if collecting cards was the "cool" thing to do, but man we had some fecking good times doing it.
