Eastern Great Lakes hide jacket, possibly Ottawa or Seneca, early to mid 19th C.
 
Native tanned hide, silk ribbon, silk embroidery, and thread.
This type of jacket is usually associated with the Northern Plains Cree, or Montagnais of Quebec.
What sets this apart is the rare use of the silk ribbon applique.
Exceptional condition with some original repairs.
