Tea at Furlongs Eric Ravilious (1903-1942)

The picture has something of this: umbrella, sunshade, summer, chair, water, tropical, leisure, vacation, sea, relaxation, beach, ocean, nature, resort, sky, sunblind, seashore.
Perhaps it’s a painting of a table with a plate of food on it and an umbrella in the middle of the picture, with a field in the background.
