I at one time tried collecting premiums, but because there seemed to be no end to them I quit. I also wrote a article for "Check the Oil!" magazine on premium glasses.
I don't believe it was a giveaway from a oil company, because if it was, their name would be all over it. This doesn't mean that it wasn't given away by some service station. Stations owners many times gave away premiums that were purchased from independent premium companies.
My assumption it was given away by Alka-Seltzer.
