This photo is dated 1884 while the last image was dated 1874, the number on the original card that I cropped. She wears the same coiffure and dress so one of the dates is a typographical error. However the Royal Collection’s notes show Adéle was active from 1865 to 1880.
From Wikimedia. Also posted to Louise von Alten-Montagu-Cavendish, Duchess of Manchester-Devonshire’s new Subalbum here.
The dress is strapless so this could be an early example of a celebrity cheesecake photo. There may be a bare-shoulder sleeve under her wrap.
