Taken in 1943 by US government photographer Alfred T. Palmer, this image was apparently used to explain the rationing system to consumers. Its caption reads:On the day rationing begins, the row of "A" stamps becomes valid. And a new row of stamps becomes good every week on Sunday: "B" the second week, "C" the third, and so on. Stamps will continue to be good after the week is over. But they will expire at the end of the month. At that time "A," "B," "C," and "D" stamps will all expire together.
