#44360 Bartholomeus Van Der Helst (1613-1670)

The picture has something of this: people, wear, man, performance, music, group, woman, portrait, veil, sitting, musician, theater, outfit, recreation, costume, singer, lithograph.
Perhaps it’s a group of people standing next to each other in front of a painting of a man holding a piece of paper in one hand and a paper in the other hand.
