Smithsonian National Postal Museum
The National Postal Museum is devoted to the colorful and engaging history of the nation's mail service, showcasing the largest, most comprehensive collection of stamps and philatelic material in the world.
Visitors enter the Museum through the lobby of the building and proceed to escalators that transport them down to the floor level of the Museum's 90-foot-high atrium. The atrium, which features three suspended airmail planes, is one of five exhibit galleries that tells the story of postal history in America.
In addition to one of the world's largest collections of stamps and philatelic materials, the National Postal Museum has postal history material that pre-dates stamps, vehicles used to transport the mail, mailboxes and mailbags, postal uniforms and equipment.
