While the trademark of this ball, manufactured by Reach Co, is largely worn off (it appears to be an official American League [Harridge] model), the single signature on it most certainly is not. This is a beautiful autograph by Detroit Tiger great Hank Greenberg, signed in blank ink and rating approximately 8/10. The ball appears faded from light exposure, not use and is generally in very good condition. The signature has Greenburg's usual parentheses around the name "Hank," and the loop on the "g" at the end of his name is elongated, apparently from a minor slip of the slugger's hand while penning the autograph.
