Portrait of Count Alexander von Mensdorff Pouilly Prince von Dietrichstein zu Nicolsburg Friedrich Von Amerling (1803-1887)

The picture has something of this: portrait, people, military, man, wear, royalty, uniform, military uniform, soldier, army, leader, outfit, medal, facial hair, mustache, authority, war, weapon.
Perhaps it’s a painting of a man with a moustache and a moustache on his face, wearing a red and black uniform with gold trim.
