Signed LOA on Yankees letterhead reads, "This letter is to verify that this is the rosin bag that was used in the game when I pitched my no hitter against the Seattle Mariners on May 14, 1996. The final score of the game was Yankees 2 Mariners 0." Doc has noted this fact in NRMT black sharpie on the bag itself, along with his signature. Rotating lucite display case is included.
