Relisted- Vintage World Fair States Exhibit brooch old gold

This interesting old pin was a souvenir of the World's Fair States Exhibit. I'm guessing it was likely made before the 1930s. It has a raised image of the States Exhibit buildings made of dark, weathered gold tone metal. It has the old style C clasp. This pin does show its age with lots of surface wear and age patina to the metal, but still really cool as is! From a smoke free home:) Measures 1.25" long. KeyJ8488pin6d4s9499
