Pacific Northwest Icon & "The Kid": Ken Griffey Jr. Autographed Seattle Mariners Teal Nike Jersey (Size XL)
Bring the most vibrant colorway in 1990s baseball history into your collection: an official Seattle Mariners Teal Nike Jersey (Size XL), hand-signed across the back number by First-Ballot Hall of Famer and baseball legend, Ken Griffey Jr.
Introduced during the golden era of Mariners baseball, the iconic northwest teal jersey became synonymous with Griffey’s dazzling acrobatics in center field, backward cap style, and majestic left-handed swing. Crafted by Nike, this size XL jersey features sewn-on Mariners team graphics, silver-and-navy chest lettering, and Griffey’s legendary #24 on the back. "The Kid" signed his name in bold marker across the rear number, creating an absolute crown jewel for shadowbox framing, an executive office display, or a top-tier Seattle Mariners fan cave.
