I have a question regarding the Ewiges Deutschland books. I currently have the 1939 edition and know that there are four more editions (1940 till 1943). I also know they were sold during the WHW campaign.
But here is my question, are all editions the same and did they just sell them every year during the WHW campaign? Or is every edition a whole new book?

I’ve been trying to find the answer myself, but my German isn’t good enough yet. The reason I ask this question is because I might want to collect all five books.

Your help is much appreciated.

Regards, Rik
