Ludvig I (1173-1231), Duke of Bavaria, Palatinate at Rehn Unknown painters

The picture has something of this: people, portrait, necklace, mustache, jacket, man, wear, brunette, coat, person, royalty, lid, facial hair, retro, goatee.
Perhaps it’s a close up of a painting of a man with a beard and wearing a red shirt and a gold ring on his left side of his face.
