Portrait of Prince EG Gagarin child. 1816-17 ES AV Mamonova, France Orest Adamovich Kiprensky (1782-1836)

The picture has something of this: portrait, people, girl, woman, child, face, baby, studio, fashion, hair, model, dress, cute, wear, beautiful, wig.
Perhaps it’s a painting of a young girl in a blue dress with her hand on her chest and her chin resting on a red pillow with a black background.
