Three-wheeler

The photo dates from 1920 and depicts Mary Dixon Palmer, who was the daughter of the U.S. Attorney General at the time.  I was interested in the scooter, which wouldn't win any contests vs. modern Razor scooters, but was probably quite a novelty at the time.

Found at Shorpy, the best source for vintage photos.   The photo at the link enlarges to fullscreen; I've just embedded a smaller version to save on my alloted space.
