Interno dello Studio del Pittore con la Giovinetta Errazuriz Giovanni Boldini (1842-1931)

The picture has something of this: people, church, man, god, vintage, saint, woman, wear, antique, veil, artistic, retro.
Perhaps it’s a painting of a person sitting in a chair in a room with a mirror on the wall and a cat on the floor in front of the mirror.
