Outstanding 1921 Exhibit card signed by popular Hall of Famer Grover Cleveland Alexander.  The signature has been elegantly applied in black fountain pen, diagonally along Alexander's image on the card.  A strong example, the card itself does exhibit some mild toning and a small pinhole at the top-center, some corner and edge wear reducing the technical grade to the FAIR level.  A highly desirable signature, on a tough-to-find card.  Authenticated by James Spence Authentication and encapsulated by Beckett when those companies had a business relationship.
