Manuel Godoy Agustin Esteve y Marques (1753-1820)

The picture has something of this: people, wear, man, portrait, costume, sword, outfit, music, cape, sash, royalty, jewelry, military uniform, weapon, military, pants.
Perhaps it’s a painting of a man wearing a black coat and yellow pants with a red sash around his neck and a gold and blue belt around his waist.
