Pontiac "Chief Of The Sixes" Bronze Promo Coin Used By Oakland Motor Car Company
Good Condition (see photos)
Diameter: 25mm
The token features a profile image of Chief Pontiac on the front and has Product of General Motors on the reverse. 
It served as a radiator emblem on Pontiac automobiles manufactured between roughly 1926 and 1931, with "Chief of the Sixes" being a marketing motto for the cars.
These tokens were generally produced in bronze or brass.
