Self-portrait and portraits of comrades Vasily Maksimov (1844-1911)

The picture has something of this: people, group, musician, music, man, singer, bassist, concert, facial hair, guitarist, performance, wear, drummer, portrait, band, audience, outerwear.
Perhaps it’s a painting of a group of men with beards and moustaches, with one of them holding his chins in his other hand.
