Greuze, Jean-Baptiste – Portrait of Count Stroganov, PA in childhood Hermitage ~ part 04

The picture has something of this: people, portrait, wear, child, girl, son, facial expression, jacket, youth, face, music, boy, man, woman, outerwear, profile.
Perhaps it’s a close up of a painting of a young girl wearing a white shirt and a white collared shirt with ruffles on the collar and a black background.
