Pieter de Hooch, Dutch (active Delft and Amsterdam), 1629-1684 – Party Philadelphia Museum of Art

The picture has something of this: people, group, wear, child, woman, man, royalty, son, room, baby, veil, two, seat, furniture, three.
Perhaps it’s a painting of a group of people in a room with a man playing a guitar and a woman standing in front of a man with a guitar.
