The Inopportune José Ferraz de Almeida Júnior (1850-1899)

The picture has something of this: people, woman, man, wear, indoors, two, furniture, veil, room, group, home, seat, lid, portrait, chair, family.
Perhaps it’s a painting of a woman in a white dress standing in front of a easel in an artist’s studio with a cat on the floor.
