I think this is one incredible photograph showing an adagio acrobatic duo performing on the top of a tank during WW2. I have no idea of the date or the name of the act or the location but it seems they are Russian troops.
Most grateful to Managers-Circus Varietes

Isn’t this a truly great photograph? From America this is the very well known trapeze artiste Gertrude Falls and the date would be the 1920s.
