Bill Lango clued me into this article on plastic premiums.
The Company Tatra Plastic at one time made the plastic premiums for the cereals in Canada, which is not being done anymore due to child safety laws. One of the premium lines they did was Warriors through the Ages. This was the figures that were done in England as Warriors of the World and here in the United States as Soldiers of the World by Rubenstein. It would be interesting to see if they have any information on who they got the mold etc.
