Boy, flying off the shelves! At a rate of about 1 per every 1000 Germans.
By contrast 400k Harry Potter books sold on the first day in Germany, and that was just the German edition. The English edition finished the year as the 3rd biggest selling book of the year in Germany.
As a historical curiosity to 4 generations who have never had access, but yet have been so impacted by the book, I find 1 in 1000 to be so low as to be rather remarkable.
Actually we did have access to it. Original copies were still in wide circulation and annotated copies were available, not to speak of the internet. If you wanted to read it, you have. I know I did, if only in parts because it's a huge bore once the novelty wears off.
