Taken by an unidentified photographer during the early 1940s, the fine print on this document emphasizes that successful rationing depends on faith and trust. There is "an agreement that the holder will observe the rules and regulations governing gasoline rationing as issued by the Office of Price Administration."
Meanwhile, the caption that accompanies this photo underlines the bureaucratic nature of such endeavors: "Gasoline ration card B3. Registrars are empowered to issue B3 cards to persons whose applications show that their vocational requirements are greater than those which the basic allotment card A provides and cannot be met by B1 or B2 cards."
