Oh my how I loved my 1989 Ken Griffey Jr. Upper Deck Rookie card as a kid (along with every other kid on the planet) and still do to this day. I can still remember getting the card in my pack and immediately putting in its plastic case where it lives today. Anyways, I came across this article on the card covering its popularity to the decision in making the card the first card in their series. Topps didn’t even include him in their set. Quite interesting.
