Napoleon-Alexandre-Louis-Joseph Berthier, Prince de Wagram and his Daughter Franz Xavier Winterhalter (1805-1873)

The picture has something of this: people, seat, furniture, baby, Renaissance, pants, royalty, opera, chair, easy chair, sit, wear, offspring, two, reclining, woman, son.
Perhaps it’s a painting of a man and a woman sitting next to each other on a red chair with a black dog on the floor in front of them.
