Big and essentially Mint 1.75" real photo button with back paper by Keystone Badge, Reading, Pa. Collet suspends ribbon with gold text "Pennsylvania's/1861-1898/First Defenders/1917." Ribbon joins to a bronze luster watch fob with eagle holding ribbon inscribed "Our Country's Defenders." Eagle stands on a shield which has enamel paint most of which remains intact. Given the date of 1917 it is probable this was a piece worn at the inauguration. First we've seen and Exc. with essentially Mint rare button.
