The 1989 Upper Deck Ken Griffey Jr. is a very iconic rookie card. I watched a documentary on sports cards but the name of it I can’t remember. It did however discover that Upper Deck continued to print this card even up to the 1990’s. So is mine a 1989??? I’ll never know.

Edited: The documentary is called Jack of all Trades. Also there is no proof of Upper Deck printing in the 90’s but watch the documentary and decide for yourself.
