Dear Britt,
I didn't take them myself, of course.
I found them in different books, especially in
Elisabeth, Stationen ihres Lebens by Brigitte Hamann and Elisabeth Hassmann, and on
www.schoenbrunn.at.
When I was in Vienna last year, I went to Schönbrunn very early in the morning. In most of the rooms I was all alone and I had enough time to look at the photographs, the paitings and the furniture closely. But anyway I didn't dare to take one single picture.
By the way: If you want to sit on a chair that once belonged to a member of the Imperial family, you have to visit the Möbelmuseum, also called Hofmobiliendepot in Mariahilferstraße. It's officially allowed to sit on certain chairs there.
