One of the most popular players of his era Hall of Famer Hank Greenberg applied his signature in his typical black felt-tip to this 1939-46 Exhibit card. The card itself has seen better days with clear tape having been affixed to the top and bottom and significant wear throughout a TTM request to autograph the card front politely written on the reverse. The signature itself authenticated by James Spence Authentication during their alliance with SGC some years ago is bold and legible underneath the image of the slugger.
