Portrait of Colonel Auguste-Frederic Bon-amour, Marquis de Talhouët Horace Vernet (1789-1863)

The picture has something of this: sword, people, weapon, lid, war, armor, warrior, cape, wear, jacket, military, uniform, knight, skirmish, pants, soldier, royalty.
Perhaps it’s a close up of a painting of a man in a military uniform with a sword in his hand and a crowd in the back ground behind him.
