An interesting photograph

The source is at: http://quod.lib.umich.edu/s/scl/x-lpf.0610/LPF0610

The metadata describes it as Jones, Ellis O. With unknown woman, standing next to car, ca. 1920.
In the Joseph A. Labadie Collection at the University of Michigan:

A collection documenting the history of social protest movements and marginalized political communities from the 19th century to the present 

In the 1930s, the U-M Library’s Joseph A. Labadie Collection — the oldest such collection in America — was called “probably the most complete record of the social unrest of our times that has ever been assembled."

No other context for the photograph is offered, but I'll see what I can discover.

If the date is correct he would be about 47 years of age.
