Vintage 1930s 10×13 matte finish black and white MGM studio portrait by Clarence Sinclair Bull, signed and inscribed across his left shoulder in black fountain pen, “To/Bennett/Sincerely/Spencer Tracy/1935.”  Fine condition, with a mild vertical bend in the background at the extreme left edge; mild creasing along the bottom of the right border; multiple pin holes to the bottom corner tips; an additional pin hole plus rust stain in the center of the bottom border; and slight paper loss to the top corner tips, the result of the photo having been tacked to a wall. The aforementioned condition issues can be matted out with minor loss to the final letter of his signature.  Scarce.
