In 1954, the producers of the original Superman TV series filmed a special 18-minute episode, “Stamp Day for Superman,” for the U.S. Treasury Department to promote stamp day savings plans for children. Savings stamps were the kids version of an adult savings bond. The savings stamps thread makes for an awkward plot device (Hint: It involves a typewriter). In the end, though, Superman foils the bad guy and gets the kids to save money.
Superman’s advice: “Be super citizens and have a super future by saving regularly with United States savings stamps at school. And keep on making me and everyone else as proud of you as we are today. Bye now.”
