nature #236 Rien Poortvliet (1932-1995)

The picture has something of this: bird, wildlife, nature, duck, water, outdoors, poultry, animal, feather, wild, mallard, river, lake, beak, avian, environment, pool.
Perhaps it’s a painting of two ducks and a duckling in a grassy area with trees in the background and grass in the foreground, and one duckling.
