My mother bought me this book so that I could practice my ability to read in German. I was approximately 9 or so and we bought it at my most favorite bookstore ever, Libri Mundi, in Quito.
The thing that I loved about this story, aside from its glorious black and white illustrations, is that it was about a little girl who puts a bolt lock on her door and how it changes the way she relates to her surroundings. I used to think I was that little girl, learning a lesson on the pages of a book. I still have that book somewhere, packed in boxes of books from long ago… but it is a book I have treasured.
I have only been able to find it on the Amazon.com site for Germany and I forgot to see if I could find it when I was last in Austria.
It is funny that the books I most fondly recall from my childhood are due to its illustrations… another being D'Aulaires' Book of Greek Myths.
