Young Woman with a Mandolin, 1865, Oil on canvas, Muse Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: people, wear, woman, seat, furniture, two, portrait, group, room, veil, music, royalty, dress, indoors.
Perhaps it’s a painting of a woman sitting in front of a easel with a painting on a easel stand.
