PRO --- PATRIE (Cleveland)

Hand-made snowshoe? promoting Grover Cleveland for president, c. 1888.  1 1/2 x 5 3/4".  Looks like a carte de visite which has been sewn into a stringed wooden showshoe.  Definitely weird and definitely from the period with hand-written letters above Cleveland's portrait.  "PRO PATRIE" (sic) = "For One's Country".
