As the United States nears its 250th anniversary, the Harry S. Truman Presidential Library & Museum presents an incomparable exhibition of rare documents that have shaped our nation and the world.

Opening the Vault: The Story of US examines the ideals, conflicts and turning points that define the American experience.
