A first day cover is an envelope containing a commemorative stamp issued on an appropriate day from a special location, and someone added artwork depicting the topic. World War II is not yet over, but on April 25, 1945 a group of nations met in San Francisco to establish an organization known as the United Nations. In this Warm Up/Review lesson, students will identify and analyze the images found on the first day cover as well as read and analyze the United Nations preamble. What words and symbols on the envelope depict the objectives of the United Nations? Why would a quote by Franklin D. Roosevelt be on the stamp when he had died earlier in the month? What was his vision for this meeting? Are the objectives stated in the Preamble still being met today? The U.N. is now over sixty-five years old. Ask students to draw a new first day cover depicting the work of the U.N. in today’s world.
