Artilleryman Saddling a Horse Henri De Toulouse-Lautrec (1864-1901)

The picture has something of this: cavalry, mammal, skirmish, ancient, cattle, people, war, vintage, battle, soldier, armor, man, warrior, seated.
Perhaps it’s a painting of a man standing next to a horse in a field with a bird flying in the sky in front of him and a tree in the background.
