Portrait of the children of the Austrian Empress Maria Theresa Aleksey Antropov (1716-1795)

The picture has something of this: doll, people, retro, woman, child, son, baby, two, princess, family, three, group, girl, portrait, vintage, dress, wear.
Perhaps it’s a painting of a woman and three children sitting at a table with a vase of flowers in front of her and a man standing next to her.
