Each is 1.5" and each is covered in minute craze lines but very subtle and barely showing. In addition the celluloid surfaces remain totally smooth and clean. We've never seen two other buttons like this. Each has brass collet on reverse with fixed bar pin. Each has paper naming maker "Shepard Photo Co/Shepard & Wilson, Props. St. Paul, Minn." Pictured are "U.S. Cruiser Columbia." Second is "U.S. Battleship Iowa." Visually, even with the almost microscopic tiny craze lines these pieces display glossy and Mint. Rare.
