I found this map on deviant art and thought that you may find it as intriguing as me. Unfortunately the map has a big water mark in the middle of the image, so at least the free access version isn’t that useful as a prop. But it really helps with understanding the geography at the time.
That map really is cool. You don’t really notice the watermark in the enlarged version. Very nice, thanks for sharing!!
Really shows how fragmented German was at the time. Great find!
