Seattle Mariners cap worn by Hall of Fame outfielder Ken Griffey Jr. during the 1990s. The teal wool Mariners cap features the team's logo on the front and Griffey's uniform number ("24") written in black marker on the underside of the brim. Located on the interior headband are a "New Era Pro Model" label, a "Size 7 1/8" tag, and a "Diamond Collection" label. Griffey has personally attested to its game use by inscribing the cap in black ink on the front "Ken Griffey Jr./Gamer." The hat displays moderate wear, including soiling to the headband. This is an outstanding Hall of Famer game-used cap worn by one of the greatest all-around players in baseball history. Full LOA from Becket (for the autograph).
