Henri Lebasque – The Papasol on the Terrace of Morgat, 1924 Sotheby’s

The picture has something of this: beach, ocean, seashore, water, sea, sand, island, vacation, relaxation, seascape, sun, paradise, resort, leisure, tropical, idyllic, recreation, turquoise, horizon.
Perhaps it’s a painting of a group of people sitting on a wall next to a body of water with an umbrella in the foreground and a sailboat in the background.
