Miss Elizabeth Williamson on a Pony Annie Louisa Swynnerton (1844-1933)

The picture has something of this: cavalry, seated, mammal, two, people, wear, horse, woman, recreation, herder, man, lid, equestrian, three.
Perhaps it’s a painting of a young girl riding on the back of a brown horse on a lush green field under a blue sky with puffy white clouds.
