Louis-Philippe and the Duke of Orleans in Versailles Horace Vernet (1789-1863)

The picture has something of this: people, cavalry, wear, veil, man, seated, weapon, group, sword, military, soldier, woman, uniform, outfit, monarch, mammal.
Perhaps it’s a painting of two men riding on the backs of brown and white horses in front of a crowd of men and women in military garbs.
