Vintage Niagara Falls Indian Chief Wall Plaque

Niagara Falls, Canada. Vintage Indian Chief wall plaque. I believe this is made out of plastic or it may be plaster but I do not know for sure. Colors are good some loss of paint on the backside of item. Would not be seen when item is hung. Item is about 21 inches long and 13 inches wide. I have no idea of the date of this item. If I was to guess I would say fifties or sixties.
