… here’s a photo with a bit of a military presence in it (Washington, DC, in 1917).
In the background: Child’s Restaurant. In the restaurant’s windows and on the sidewalk: people watching the motorcade pass by. In the street: a motorcade carrying some foreign dignitary to or from a meeting. The cars are flanked by military men on horseback and by what appear to be policemen on bicycles.
And in the foreground, a skinny horse hitched to the West End Laundry’s delivery van.
I lived near and worked in DC for nearly ten years, and I can tell you that modern motorcades cause a bit more fuss and congestion than this one seems to have done.
