Ralph Sheldon Hieronymus Custodis (1589-1598)

The picture has something of this: people, man, wear, portrait, music, indoors, fashion, musician, movie, dinner jacket, outfit, recreation, theater, military, menswear, intelligence, retro, singer.
Perhaps it’s a painting of a man in a black coat with a white collar and a ring on his left hand and his right hand in his other hand.
