Owney (ca. 1887 – June 11, 1897), was a terrier mix adopted in the United States as a postal mascot by the Albany, New York, post office about 1888. The Albany mail professionals recommended the dog to their Railway Mail Service colleagues, and he became a nationwide mascot for nine years (1888–1897). He traveled over 140,000 miles throughout the 48 contiguous United States and around the world as a mascot of the Railway Post Office and the United States Postal Service. He was the subject of commemorative activities, including a 2011 U.S. postage stamp.

The Postal Square Building (formerly the City Post Office) served as the main post office for the city of Washington, D.C., from the building's completion in 1914 to 1986. It now houses the National Postal Museum, the Bureau of Labor Statistics, and offices of the United States Senate. Architect Daniel Burnham designed the building in the Beaux-Arts style—the same style Burnham used for the neighboring Union Station. Construction for the Postal Square Building began in 1911 on a lot near the Capitol. Planning began with a 1901 proposal by the Senate Parks Commission. The commission called for three buildings to mark the northern end of the Capitol complex. While the first two buildings in the plan, Union Station and the Postal Square Building, were completed early in the 20th century, the 1901 plan would not be fully implemented until the completion of the Thurgood Marshall Federal Judiciary Building in 1992. A major renovation from 1929 to 1935 expanded the building for increased mail processing and service capacity. By the 1950s, renovations had removed many of the Beaux-Arts features of the building. The main hall and lobby area only showed traces of their former grandiose design with modernist elements replacing the Beaux-Arts style. The building received another major renovation in the early 1990s, during which the original appearance of the lobby and main hall area was restored. The National Postal Museum moved into the building in 1993 following the renovations. The Bureau of Labor Statistics and the Capitol City Brewing Company also moved into the building during the 1990s. (Capitol City Brewing Company closed in 2011 to make room for an expansion of the National Postal Museum.)
