Mein Kampf cover font - WWII Black Letter Propaganda Face

Hi everyone, I wonder if anyone knows the primary face used in this cover of Mein Kampf. The question was asked on another forum and was never answered. The asker mentioned that the cover is a reproduction and that the face is probably available digitized. I'm specifically interested in the black letter face used for the styling of "Mein Kampf" in particular. Here is the original post.

And Here is a link to the image, which I am posting below as well.
