National Postal Museum

The National Postal Museum was established by an agreement between the Smithsonian and the United States Postal Service in 1990. However, its extensive collections of stamps and other philatelic materials date back to 1886. The Postal Museum is housed in the lower level of the former Washington City Post Office Building, which was built in 1914. The postcards in this gallery show the Post Office Building shortly after it was built.
