This is an absolutely stunning pin that was created in West Germany, a powerhouse for mass produced costume jewelry after WWII. It is a lightweight and molded hard plastic dahlia. Unike Japanese imports from the same time period, who made these types of pins with celluloid, this creation is more lightweight and precise in its imagery. It's the perfect gift for a gardener or somebody who just appreciates simple beauty. Diameter is 2 1/4" and signed Western Germany on back.
