Lina Fuhr-Waldau Julius Baumann (1800-1858)

The picture has something of this: wear, portrait, people, woman, veil, jewelry, fashion, facial expression, retro, girl, model, lid, actress, music, outfit, dress, outerwear, festival.
Perhaps it’s a painting of a woman in a black dress with her eyes wide open and her hair in a bun, looking to the side, with a blue sky in the background.
