Ken Griffey Jr. Seattle Mariners "Turn Back the Clock" replica jersey, signed by Griffey in black Sharpie (grading 9/10) on the left breast. This piece was signed by Griffey under the auspices of Upper Deck and is accompanied by a UD hologram label (affixed on the manufacturer's label) and corresponding COA. This was a limited-edition issue by Upper Deck and is hand-numbered "68/240" in black marker on the left front tail. However, as noted in a copy of a letter from Upper Deck to the original owner, the limitation number on the jersey is incorrect. These signed "Turn Back the Clock" jerseys were limited in number to only 124, and only 124 hologram numbers are listed in the UD database for this jersey. The jersey (size 48), manufactured by Mitchell & Ness, remains in Mint condition. Housed in its original Upper Deck box.
