1988 San Bernadino Spirit Ken Griffey Jr Signed Minor League Pre Rookie Card BAS Beckett 10

You are looking at a 1988 San Bernadino Spirit Ken Griffey Jr signed minor league card! This card is super rare and unique in that it's 1 year prior to his rookie cards that debuted in 1989. Signature and card are very nice, signature was graded a 10 by Beckett (BAS)! I will ship out well packed, fully insured within 1 business day of purchase. Thank you very much!
