Check this out. Look familiar? This mode of transportation closely resembles the Segways you see zipping around D.C., carrying tourists around the sites. Or maybe a little like those Razor Scooters.
Washington, D.C., circa 1917. “Post Office postmen on scooters.” Kind of a Segway vibe here. Harris & Ewing Collection glass negative.
You should also recognize this location as the Post Office building next to Union Station.
