At the Races Gentlemen Jockeys Edgar Degas (1834-1917)

The picture has something of this: cavalry, seated, people, mammal, transportation system, lithograph, group, two, horse, livestock, carriage, man, veil, herder, saddle.
Perhaps it’s a painting of a group of people riding on the backs of horses in a field with a carriage in the foreground and a horse drawn.
