English King Charles I in three angles Anthony Van Dyck (1599-1641)

The picture has something of this: people, group, wear, portrait, music, musician, facial expression, two, three, retro, man, affection, woman, theater, singer, necklace.
Perhaps it’s a painting of three men, one with a mustache and the other with a moustache, standing next to each other in front of a cloudy sky.
