This 5¢ red U.S. Airmail stamp, issued in 1948, commemorates the 50th anniversary of Greater New York City’s consolidation (1898–1948). The design depicts a map of the five boroughs—Manhattan, Brooklyn, Queens, Bronx, and Richmond (Staten Island)—encircled by a ribbon inscribed with the anniversary dates. Surrounding the map are stylized airplanes, symbolizing progress and the importance of aviation in connecting the metropolis with the world. Printed in bright carmine red, it was part of the U.S. Post Office’s post-war emphasis on airmail. A sought-after issue for collectors of airmail history, New York City memorabilia, and commemorative U.S. stamps.
