The Races in the Bois de Boulogne Édouard Manet (1832-1883)

The picture has something of this: cavalry, people, seated, horse, group, race, vehicle, lithograph, motion, transportation system, mammal, competition, many, equestrian, hurry, man.
Perhaps it’s a painting of a horse race with jockeys and horses in the middle of the track and a crowd of people on the side.
