A first day cover is an envelope containing a commemorative stamp issued on a an appropriate day from a special location, and someone added artwork depicting the topic.This Warm Up/Review lesson is based on the images found on an envelope, postmarked on July 4, 1942. It has been almost seven months since the attack on Pearl Harbor. Even the U.S. Post Office got into the propaganda business by issuing patriotic stamps. Each World War II stamp supported the effort to Win the War. How will the nation celebrate its birthday when it has entered into a world war? Students will identify and analyze the propaganda symbols in both the stamp and artwork. How did the Post Office and the cachet/artist encourage citizens to help win the war against the forces of aggression? Students will also discuss the words used to unite the nation in its struggle to save democracy. The concluding activity asks students to draw a stamp or first day cover for July 4, 1945.
