Joseph-Marie (1706-1747), Duc de Boufflers Jean Marc Nattier

The picture has something of this: people, portrait, man, woman, wear, retro, indoors, royalty, jacket, veil, music, sword, Renaissance, child, smoke.
Perhaps it’s a close up of a painting of a person wearing a suit of armor and holding a sword in one hand and a glove in the other hand.
