Hank Greenberg had a momentous 1946. In his first full season back from military service, he swatted 44 home runs and drove in 127 runs, so much for that layoff. This index-card-sized offering was signed by the Hall of Famer in 1946 and marked on the reverse. The signature was signed in black felt pen and rated a perfect "10".
