Henri Rousseau – Rendezvous in the Forest National Gallery of Art (Washington)

The picture has something of this: tree, fog, dawn, leaf, mist, fall, landscape, nature, sunset, sun, wood, silhouette, branch, sky, fair weather, winter, countryside, flora.
Perhaps it’s a painting of a man and a woman in a wooded area, with trees in the foreground and a bird in the sky in the background.
