Nice studio portrait, with some puzzling elements. First of all, we don’t know when the picture was taken, even if one of the portrayed men (named Enrico) has dated the picture and there’s the date on the stamp too. For both, the day and the months are identical: September 18th. The point is this Enrico dated it 1919, whereas the stamp indicates 1921.
The seated man wears a traditional Army NCO uniform, with the Fatiche di Guerra ribbon (see my yesterday’s post), whereas the standing man wears a fatigue uniform, probably used in the navy (keep in mind that we’re in Taranto, an important military harbour).
Lat but not least, I’ve discovered that I may have in my collection another picture taken in the very same studio, as the tiles are identical!
