Catalog notes There is also a letter, together with the envelope closed with the royal seal. The five-page letter is addressed and hand-written by Emperor Franz Joseph. It was mailed for Godollo, Hungary the 8th of November, 1898. Two paragraphs of the letter are quoted on page 370 of the book, Briefe Kaiser Franz Josephs an Frau Katharina Schratt, which was printed in Vienna in 1949. The book written by Hermann Mailler, Frau Schratt, Ein Lebenbild, was printed in Vienna in 1947, and describes the love affair of the Emperor and the actress. The Emperor's handwritten letter was dated at Godollo, the royal hunting castle in a small suburb of Budapest. It was one of the favorite hunting perserves of the Emperor.

Perhaps the most interesting book relating to this royal affair is the volume Anna Nahowski und Kaiser Franz Joseph, Aufzeichnungen, which was published in 1986 in Vienna. From it, we found out that Emperor Franz Joseph had a torrid, purely sexual affair with a married woman, Anna Nahowski, born Nowak. She was married shortly after her 15th birthday to a drunkard who beat her and tortured her until she finally got a legal separation. In her book, she gave a detailed but not "explicit" description of her sad love story with the Emperor, who usually visited her at 4:00 a.m., quickly made love and disappeared. The affair went on for years. Anna Nahowski had no idea that her imperial lover spent a short time in the afternoons in the boudoir of K. Schratt, until age forced him to choose. He chose the actress K. Schratt. Anna Nahowski, the mother of his illegitimate daughter (who later became the wife of the well-known Austrian composer, Alban Berg), was paid off with a royal sum.
