Claude Monet – Bazille and Camille (Study for “Dejeuner sur l’Herbe”) National Gallery of Art (Washington)

The picture has something of this: people, woman, wedding, wear, man, two, veil, dress, lid, girl, group, portrait, bride, three, child, tree.
Perhaps it’s a painting of a man and a woman standing next to each other in a wooded area, with a dog on a leash in the foreground.
