You're packing on the years if you remember those World War II rationing rules. Everything was rationed from sugar to meat to one of our most needed commodities: gasoline. Depending upon your status, you had a specific amount of gas per week allotted to your family. The common ordinary citizen had the "A" card as shown above stuck on the windshield of his auto. The "B" card holder could get more if he or she proved that she had to have more gas for commuting, etc. There were special windshield stickers for "E" mergency workers, etc.
