William Matthew Prior – Boy with Toy Horse and Wagon National Gallery of Art (Washington)

The picture has something of this: child, wear, girl, woman, people, portrait, skirt, retro, toy, fashion, doll, model, son, dress, pants, lid, cute, costume.
Perhaps it’s a painting of a little girl in a brown dress holding a string and a toy car in front of a curtained area with a red curtain.
