Head boy Uzbeks. 1921 Kuzma Sergeevich Petrov-Vodkin (1878-1939)

The picture has something of this: people, portrait, wear, facial expression, man, son, side view, child, woman, girl, face, profile, leader, veil, indoors, pensive.
Perhaps it’s a painting of a woman’s head with braids in her hair and a white shirt on the left side of the painting is a portrait.
