Vintage offers 1940s Era Sterling Silver Leaf Umbrella Brooch Pin

This is a vintage sterling silver leaf umbrella brooch from the 1930s - 1940s era that is unique and one of a kind. It is marked "Ster" very faintly on the handle and tests positive for sterling silver. The pin back opens and closes as it should. The brooch uniqueness and style tell offers me it's from the 1930s or 1940s. Sold as is.
