Lot #32:

1999 Ken Griffey Jr. Seattle Mariners Signed Game Worn Alternate Jersey (MEARS A10 / JSA) Attributed to Career Grand Slam #11 via Inscription

Offered is a Seattle Mariners alternate jersey dating to Ken Griffey Junior's 1999 season with the team which has been signed on the reverse numeral four by Ken along with a "To Super Joe All My Best GS #11 4-30-99" inscription. Griffey's home run log shows him hitting career grand slam #11 on Sunday April 29th with available images confirming the Mariners wore this alternate style jersey during that game. He did hit career grand slam #12 the next day on the inscribed 4-30-99 date, but the Mariners wore their home whites for that game leading us to believe he accidentally inscribed the wrong date. Majestic and size 46 tags sewn to tail while "Mariners", number 24, "Griffey", and a team logo patch are also sewn to the navy mesh jersey. Moderate wear. MEARS A10. (04C0107)
