Dedreux, Alfred – Le comte de Paris et le duc de Chartres dans le parc de Claremont Château de Versailles

The picture has something of this: cavalry, seated, people, man, mammal, two, horse, woman, recreation, wear, group, equestrian, veil, herder, child, three.
Perhaps it’s a painting of two boys riding on the backs of horses in a wooded area with a fallen tree in the foreground and another boy sitting.
