Kardovsky, Dmitrii Nikolaevich – Ball at the St. Petersburg Nobles February 23, 1913 Hermitage ~ Part 05

The picture has something of this: people, many, crowd, group, ceremony, festival, city, woman, man, celebration, wear, street, parade, public show, leader, event, prayer, tourist.
Perhaps it’s a painting of a crowd of people standing in front of a stage with a man in a red suit and a woman in a white dress.
