Wonderful Vintage German Souvenir Celluloid Hat Pin or Brooch, featuring the German city of Triberg im Schwarzwald. The pin features a cuckoo clock, with little suspended brass metal weights. I think these hat pins are celluloid, but not certain; they are some type of plastic.There is a little brass pin closure on the back. 2 -1/2″ x 1 -1/4″ Very good vintage condition. Sorry, no sales outside the U.S.
