Portraits of two extraordinary oxen, the property of the Earl of Powis James Ward (1769-1859)

The picture has something of this: mammal, cattle, cow, bull, livestock, horn, animal, farm, agriculture, herd, milk, beef cattle, calf, two, skull, rural.
Perhaps it’s a painting of a couple of cows standing next to each other in front of a building with a cow in the foreground and another.
