Sailing boat in a cubist landscape Boris Grigoriev (1886-1939)

The picture has something of this: food, water, brush, acrylic, river, fish, sea, creativity, nature, watercolor, coloring, landscape, paintbrush, outdoors, artistic.
Perhaps it’s a painting of a landscape with hills, trees, and a man with a shovel in the foreground, with a blue sky in the background.
