Portrait of Grand Duchess Anna Pavlovna and Grand Duke Nikolai Pavlovich, children of Emperor Paul I Vladimir Borovikovsky (1757-1825)

The picture has something of this: people, child, furniture, son, two, woman, baby, seat, family, group, sculpture, room, man, girl, reclining, three.
Perhaps it’s a painting of a boy and a girl sitting on a bed with a dog in the foreground and a cat on the other side of the bed.
