Antoine-Marie-Philippe-Louis d´Orleans, duc de Montpensier Franz Xavier Winterhalter (1805-1873)

The picture has something of this: wear, people, man, military, weapon, uniform, portrait, military uniform, soldier, outfit, veil, lid, sword, smoke, war.
Perhaps it’s a painting of a man in uniform standing in a field with a sword in his hand and a building in the back ground and a cloudy sky in the background.
