THE M&M BOYS: A PROFILE IN CIVILITY is how presidential historian Michael Beschloss described them more than half a century later, harkening back to a golden age in baseball and America that Roger Maris and Mickey Mantle helped define every bit as much as John F. Kennedy.

MARIS & MANTLE: Two Yankees, Immortality and the Age of Camelot is the first, epic and true story of the Roger Maris and Mickey Mantle friendship forever intertwined in baseball history thanks to the unforgettable 1961 season, when the two Yankee icons spurred each other to new heights in pursuit of Babe Ruth's home run record. History has largely overlooked the bond between the two men not as titans of their sport, but as people.
