This is…..Brilliant!!
My niece is a Aboriginal Canadian. She works for the Six Nations reserve here in Ontario. I will show her this photo and see if she can give me some info on your details. If she doesn’t know, she will make every effort to find out. I’m pretty sure this is most likely a ceremonial headdress. But not sure of the significance of what it was used for.
