Flora Fredinand Keller (1842-1922 : 1809-1861)

The picture has something of this: people, woman, wear, girl, portrait, nude, reclining, dress, fashion, man, model, veil, music, sexy, war, brunette.
Perhaps it’s a painting of a woman in a dress and hat holding a bouquet of flowers in front of a tree with a bird sitting on top of it.
