Dear Daniela,
1) I have many (rare) books with lots and lots of pictures in it and some royal postcards. But I found most of the pics somewhere in the internet, especially on ebay. For the most beautiful pics you have to go to the "Österreichische Nationalbibliothek" in Vienna. There is the so-called "Bildarchiv" where you can find pics of almost every royal. The people who work there are very nice. (BTW: I have only one CDV, because they are really expensive. It shows Duchess Maria Theresia of Württemberg, Archduchess of Austria).
2) Görz is in Tirol, Austria. Maria Annunziata had problems with her lungs and the climate there was better for her health.
3) Otto caused Maria Josepha some embarrassing situations. One day he went with the men, he usually drank bear and wine with, into the bedroom of his wife and said: "Look at this nun."
Soon after their marriage, Otto and Maria Josepha went separate ways. He lived with one of his mistresses and Maria Josepha lived with her sons Karl and Maximilian in the Augartenpalais, Vienna. Today this is the residence of the "Wiener Sängerknaben".
Otto had relationships to Marie Schleinzer and Louise Robinson. He was the father of the illegitimate children Hilde and Alfred. Maria Josepha herself had a relationship to famous Austrian actor Otto Tressler who even played in "Sissi I".
When Otto became seriously ill, Maria Josepha didn't care. After his death, she instructed Otto's servants to disinfect the room. Otherwise she wouldn't have entered the room.
