The Luxembourg Garden at Twilight John Singer Sargent (1856-1925)

The picture has something of this: people, vehicle, group, woman, wear, cavalry, carriage, two, man, city, home, road, ceremony, street, transportation system, many, outdoors, recreation, cart.
Perhaps it’s a painting of a man and a woman in a formal dress standing next to each other in front of a formal garden with a fountain in the background.
