1989 was Ken Griffey Jr's rookie year playing baseball for the Seattle Mariners. This fine, gray jersey was worn by the 600HR hitter that very season. It has a Rawlings size 44 tag and a "Set 1 1989 flag tag" stitched inside the front tail and Griffey Jr. has signed the front in mint blue Sharpie with the inscription "24". Purchased directly from Barry Wolfsheimer in 1990 who acquired jerseys directly from the Mariners. Nice jersey from one of modern baseball's greats.
