Description:Lot of (3) possibly autographed baseball player cabinet photographs c.1890s. Trio of cabinet cards have each likely been signed by the subject. Includes Bob Glenalvin ("Comp R J Glenalvin" on lower front), Frank Connaughton (lengthy 1895 dated handwritten and inscribed sentiment on back), and Mike Sullivan ("Yours Sincerely, Michael Joseph Sullivan" on back). Mild to moderate scattered toning and wear. Due to the obscure nature of these "signatures" and lack of comparative exemplars they are offered without formal/definitive authentication however given the nature of the pieces we believe that they are likely authentic: GD/VG-VG/EX
