Nature #18 Rien Poortvliet (1932-1995)

The picture has something of this: animal, nature, portrait, zoo, head, mammal, wildlife, face, goat, sheep, wild, eye, cute, baby, fur, hair, ram, mouth, nose.
Perhaps it’s a painting of a ram with long horns standing in front of a blue sky with a tree branch in the foreground and bare branches in the background.
