Portrait of Henri Achille, the artists son Achille Zo (1826-1901)

The picture has something of this: child, wear, people, portrait, son, boy, girl, school, lid, pants, retro, adolescence, two, facial expression, sweater, model, music, education, fashion.
Perhaps it’s a painting of a young boy in a black outfit with red socks and a red bow tie, standing in front of a beige background with a brown backdrop.
