1920s 1930s vintage sterling silver powder compact w/ guilloche enamel floral design

Marked sterling compact with guilloche enamel lid, glass mirror inside. This is probably 1920s or 30s at our best estimate.

This measures about 2" in diameter. It's tarnished (we haven't cleaned or polished it) but otherwise in very good condition. The enameling looks excellent, very little wear even at the edges.
