The elaborately scripted M's in Mickey Mantle's signature exhibit tendencies toward greatness. Any handwriting analysis can tell you that, or is just the Mantle fan in us? The Mick autographed this Rawlings Diamond Collection Yankees road jersey with the same flair he strutted in his Hall of Fame career. Gray polyester has Mantle 7 on the back and New York on the front. The signature is under "York." We love those M's. You'll love this jersey.
