Great duo of signed baseballs spans three decades of New York Yankees greatness. 1) Joe DiMaggio's signature in 8-9/10 blue ballpoint ink graces the sweet spot of this Official American League (Brown) baseball. Stampings are clear and ball is in EX-NM condition, having evenly toned to a cream color. 2) Mickey Mantle has signed the sweet spot of the Official American League (Brown) ball in 7-8/10 blue ballpoint ink. Ball is in EX+ condition, with some small areas of toning breaking up the otherwise-white canvas. Though differences in personality on-and-off the field reportedly caused friction between the two legends in later years, DiMaggio (1936-51) and Mantle ('51-66) accounted for over 30 years of the most dominant center field play in Major League history.
