Cafe. 1901 Konstantin Alekseevich Korovin (1861-1939)

The picture has something of this: people, group, many, wear, man, woman, crowd, music, vehicle, child, festival, group together, recreation, flame, several.
Perhaps it’s a painting of a group of people sitting at a table in front of a tent with a red flag hanging from the side of the tent and people standing on the other.
