This is a mystery to us. We went looking for an O.Miller in our NA directories online and could find nothing. This was purchased at a sale containing a lot of American Southwest and NA jewelry. Lending to the confusion is the mechanism for the barrette that is labeled Made In France though the mechanisms tend to be an add on to the piece itself and can come from anywhere. If you think you can help us more accurately identify this item, we welcome your assistance. We believe this is more Native American ?Inspired? than actual Native American but it?s just a gut feeling. We have not ruled anything out. We do know it?s a barrette! Will ship USPS with tracking to winning buyer
