This World War II poster was created in 1942 and reads "Liberty Lives On/450th Anniversary of the Discovery of America. 1492-1942." A swashbuckling Columbus and his crew see a vision of Lady Liberty welcoming them to the New World.

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.
