Ken Griffey Jr.'s iconic 1989 Upper Deck rookie card (#1) showing him in a Seattle cap with a bat. The card is from Upper Deck's debut 1989 set, notable as Griffey's high-demand rookie and one of the set's flagship issues; design elements include the small OF position box, green/gold top border treatment and the circular 'Rookie' star logo. This appears to be the standard base printing (no parallel visible).
