When you think of the great home run hitters of the second half of the 20th century, the three names that immediately come to mind are Hank Aaron, Mickey Mantle, and Willie Mays. Each of the three autographed baseballs are near mint, are beautifully centered on the sweet spot. The Mick's single was acquired at a 1991 card show appearance in St. Louis. The Aaron signature is on a Leonard Coleman NL ball, and the Mays is on a William White NL sphere. Only 1931 bombs between the three. Enough said.
