John Newton Mappin (1800-1884) Thomas Jones Barker (1815-1882)

The picture has something of this: people, wear, man, lid, veil, portrait, two, walking stick, mammal, woman, mustache, weapon, leader, outfit, recreation.
Perhaps it’s a painting of a man wearing a top hat and holding a cane and standing next to a dog in a wooded area with trees in the background.
