Mr and Mrs A Mosselman and their Two Daughters Alfred Dedreux (1810-1860)

The picture has something of this: cavalry, mammal, people, two, woman, seated, man, group, cattle, livestock, horse, carriage, wear, seat, recreation, outdoors, child, transportation system.
Perhaps it’s a painting of a group of people riding on a horse drawn carriage in a wooded area with a dog laying on the ground next to the carriage.
