"Hammerin' Hank" Aaron spent 21 seasons with the Milwaukee and Atlanta Braves in the National League before playing for the Milwaukee Brewers of the American League for the final two years of his career. In 1999, The Sporting News ranked Aaron fifth on their "100 Greatest Baseball Players" list. He held the MLB record for career home runs for 33 years, and he still holds several MLB offensive records. He hit 24 or more home runs every year from 1955 through 1973, and is the only player to hit 30 or more home runs in a season at least fifteen times.

This Rawlings official National League baseball was signed in blue ballpoint pen by Aaron and includes a letter of authenticity from JSA. There is some yellowing to this ball as seen in the photos.
