A c.1880 CDV by Napoleon Sarony of New York of actress and 1880s "it" girl Maud Branscombe. A great example of Sarony's style and masterly use of light.

The historical Miss Branscombe has proved much harder to pin down -
apparently she was an English clergyman's daughter who jilted her
fiance at the altar, changed her name, and became an actress - at
least, that is what a slightly tongue in cheek contemporary profile in
the New York Times states. She's also name checked twice in James
Joyce's novel 'Ulysses'. One of the most photographed women of her
day, she seems to have come from obscurity - back into which she
likewise later disappeared.
