This 1943 Navy recruiting poster features heroic Messman Third Class Doris "Dorie" Miller, the first African American to be awarded the Navy Cross, the third highest honor awarded by the U.S. Navy at the time. Doris Miller was honored for his bravery during the attack on Pearl Harbor.

During World War I, many branches of the federal government used posters to urge Americans to support the war effort. In a time without radio, TV, or the Internet, posters were an inexpensive way to deliver powerful messages to millions of people. The government hired well-known artists to create designs that unified the American people. Posters continued to be published during World War II, and new posters are still in production. The National Archives holds close to 20,000 posters produced by military and civilian agencies.
