The 1963 Yankees posted a 104-58 record en route to the American League pennant. From that special season comes this very clean, Official American League (Cronin) baseball that is in EX-MT-plus condition. But the highlight here is that Mickey Mantle and Roger Maris signed on the sweet spot (label) together. Packed with 30 signatures that average 7.5/10, they include: Berra, Blanchard, Sain, Bouton, Kubek, Tresh, Richardson, Houk, Hegan, Lopez, Pepitone, Boyer, Ford and Elston Howard, who became the first African-American player ever to win the American League MVP award that season. Comes with PSA LOA.
