Menton. Beach with umbrellas Zinaida Serebryakova (1884-1967)

The picture has something of this: people, umbrella, sunshade, tent, furniture, wear, group, beach, chair, woman, man, seashore, seat, sunblind.
Perhaps it’s a painting of a group of people sitting on a beach next to a body of water with an umbrella over them and people standing on the beach.
