I found this photo is an antique store in Alabama. The back of the photo says taken by the fountain which is in the center of Place de la Concorde.
This is The Fountain of River Commerce and Navigation, one of the two Fontaines de la Concode (1840) on the Place de la Concorde, Paris, France. In the background is the Hôtel de Crillon and to the left is the Embassy of the United States of America. I believe this was taken in the 1940s during WWII.
If any one recognizes any of these men, please let me know!
