This is what I can find about her, "Anna Maria Francisca de Paula Leandra (Vienna 26 Feb 1846-Prague 22 Apr 1924); m.Vienna 22 May 1864 Georg Christian Fst von Lobkowitz (Vienna 14 Mar 1835-Prague 22 Dec 1908)." (From www.angelfire.com/realm/gotha/gotha/liechtenstein.)
From josefnovak33's photostream on flickr. The lower right corner of the image was blistered so I suppressed the damage with Photoshop, resulting in an out of place section of carpeting there. I also used Photoshop to fix spots throughout the image and smudges in the background and I also removed the sepia tone.
