This copper pin is hand-constructed with architectural elements and securely set with a copper disc enameled in turquoise. It features a cone at each corner set on intersecting bands that are curled at each end. The square panel supporting all the pieces has a hammered look with slightly curved corners. There is a deep reddish patina to the copper, and some white areas of oxidation. The back bears the impressed name of Jean Augis, a Lyons, France, jewelry designer and master metalsmith most active during the 1930s. The curled C-clasp on the back is a bit distended, and the pin stem is a bit loose, but it still holds securely. The pin measures slightly over 1 3/8 inches square.
