The Smithsonian’s National Postal Museum offers exhibits tracing the history of the postal system in the United States. It houses nearly six million postal-related items — mostly stamps, but also postal stationery, greeting cards, covers and letters, mailboxes, postal vehicles, handstamps, metering machines, patent models, uniforms, badges, and other objects related to postal history and philately. The museum’s library, with more than 40,000 volumes and manuscripts, is open to the public by appointment. In 2013, the William H. Gross Stamp Gallery — the largest in the world — opened at the museum.
