Armand Guillaumin – Madame Guillaumin and Her Son Andre, 1899 Sotheby’s

The picture has something of this: people, child, portrait, vintage, man, two, family, wear, son, retro, antique, baby, painter.
Perhaps it’s a drawing of a woman and a child sitting at a table with a plate of food in front of a window with a mountain view in the background.
