International Fiberglass made three kinds of Native American you could order. One was a brave with a bare chest and normally one or 2 feathers and a serious face. This version seems to be the more common today. 
The second was almost the same but actually had a different head mold with a fierce facial expression and a full headdress. Other then the head both versions are the same from the neck down. The third came with a necklace and a tomahawk and a few other differences and is the most rare out of the three. One of the Chief versions can be found in the small town of Montpelier, IN and he has lived here since January of 1984 and his history and how he got here and where he came from is fascinating.

My dad was one of the used car manager at Dave Waite Pontiac. Dave and his father were out west and found the Indian that stood on their used car lot for many years. I think it was the mid 60’s when the Indian first arrived at 64th and Keystone. Dave Waite Pontiac was the first Pontiac dealer to have the Indian. It was not Pontiac’s idea, it was Dave Waite and his father’s idea.

the address was 54th and Keystone. I mistaking wrote the 64th
Interesting? So they decided it was a good fit for a Pontiac Dealership and started the trend? How did the movement spread to other dealerships after that? Did Pontiac jump on the idea or was it just word of mouth?
