From 1947 - 1953 Henry J. Kaiser used the bison and the letter "K" as his hood, radiator and steering wheel hub emblem. Just another example of the bredth of the imagery that the bison portrayed in American ... and elsewhere
These rings are a copy of that emblem .... not sure when or where the rings were created. They are not super expensive, but they are pretty rare and dang neat Americana.
I do also have some of the hood ornaments, the horn hub covers and the radiator emblems should you be interested. Just call or email
