Pierre-Eugene Montezin – Promenade des Anglais, Nice Sotheby’s

The picture has something of this: people, group, tree, beach, palm, many, seashore, vacation, resort, water, tropical, leisure, island, recreation, man, outdoors, sand.
Perhaps it’s a painting of a group of people walking on a beach next to a body of water with palm trees in the foreground and a mountain in the background.
