George Henry Harlow, English, 1787-1819 – Portrait of the Leader Children Philadelphia Museum of Art

The picture has something of this: people, woman, wear, group, man, veil, girl, child, costume, son, indoors, portrait, dress, mammal.
Perhaps it’s a painting of a man, woman, and two children posing for a picture with a donkey in the foreground and a man in the background.
