i acquired the photo scanned here because i suspected it showed the Bolshoi Ballet's Nadezhda Pavlova, whom i most fondly remember from the 1970s and who burst onto the international scene after winning a ballet competition in Moscow before then appearing at the Metropolitan Opera House with a contingent of Bolshoi Ballet dancers in the summer of 1973.
for a hardly crisp or clear photo of Red Square at night with its leaping dancer, (Pavlova?), makes up in life-force what the photo lacks in resolution.
i have no idea what the occasion of the photo was. there are no annotations whatsoever on the print.
