Every year I try to attend the Vintage Textile, Costume and Clothing show at the Pickwick Bowling Alley in Burbank, California. Although I have purchased clothes at the show, I am more interested in the odds and ends that vintage clothing dealers happen across. They have a great eye and can turn up some pretty interesting stuff.
Seems they are lower teeth from a plaster medical model. These would make a hell of a bolo tie!
