Leopold, King of the Belgians Franz Xavier Winterhalter (1805-1873)

The picture has something of this: portrait, people, wear, woman, music, fashion, man, model, pants, musician, outfit, retro, chair, dress, jewelry, punk, necklace, indoors.
Perhaps it’s a painting of a man in a uniform with a hat on his head and a sword in his other hand, standing in front of a column.
