Sometime around 1910, three young men posed for a photograph at the studio of Gianakis & Svolos on State Street in Chicago.

The three are attired in fanciful costumes suggesting the wild west.

Behind them, the studio set looks like an ersatz saloon wall.

I am fairly confident that these furnishings are studio props, and that the studio specialized in souvenir postcards such as this one – like the photo booths at amusement parks or a Boardwalk arcade.

(The days of long cattle drives, which once brought beef to Chicago, were long passed by 1910.  The railroads replaced this part of cowboy culture.)

Sadly, there is no inscription that might identify the newly-minted cowboys.

The photograph was never mailed, so we lack those clues about the men or the place they called home.

It seems the photograph was preserved by one of the men as a souvenir of a trip to Chicago.

One hopes that our “cowboys” enjoyed their visit to Chicago and that they prospered in the twentieth century.
