The Victoria and Albert Museum and collaborating business put together an outstanding on-line exhibit of photographs, including court and debutante dresses, taken by the Lafayette Photographic Studio about a decade ago. That on-line exhibit was removed and a limited exhibit remains. They did not want those photos posted and I had to take them down when I had posted them several years ago. I was accused of posting images from their exhibit more recently when I had found the image elsewhere on the Internet. Others have found these images. This and a number of other images are posted on liveinternet.ru/users/arin_levindor/post113079788/.
The current limited exhibit has these notes, "Only daughter of Baron Adh?mar von Linden, Chamberlain to the Emperor of Austria Occasion: The Drawing Room, 13 May 1898: presented in the Diplomatic Circle by Mme. de Bille, wife of the Danish Minister." I cannot find anything about her or Adhümar von Linden in thepeerage or on Google.
