Portrait of a Boy Holding a Book Giovanni Battista Tiepolo (1696-1770)

The picture has something of this: people, wear, two, portrait, facial expression, man, child, woman, girl, indoors, side view, affection, interaction, son, outfit, group, outerwear, music.
Perhaps it’s a close up of a painting of a boy in a white shirt with a black cat on his shoulder and a yellow collar around his neck and chest.
