This is an adorable little vintage pin. It is a goldtone cocktail shaker wet with clear, blue, green and red rhinestones. It measures approximately 7/8"H and is unsigned. It could be unmarked Coro. It is in good condition. The photos are highly magnified and make this piece look dark in places. This is not the case when seen in person.
A great little piece for a man or woman to wear to a cocktail party!
