street scene of Detroit in 1910, with touring cars, a street car equipped with a people catcher, and a 1910 Hudson Model 20 touring car taxi parallel parking

One amazing movie theater display for a Hitchcock flick, and a interesting taxi on the street in front

Look close at the rear window area of the taxi... Only Steve B nailed the question I had about it. It's a Checker Model A, 1939 to 41 (this will be a new post)

a Chicago taxi (hack) stand in 1936
