Interesting original 1939 Flieger-Kalender. Sort of a flight themed almanac. A handful of pages are been partly or fully cut out. I believe I saw at least 3 such pages when flipping through it. It has a whole lot of ads in it and many are interesting. There are also loads of articles about flight past present and future, including plans for an underground airfield. The back page or two in the back of the book have pulled away a bit from the back side of the spine, they are not detached completely or anything just pulled up from the staple binding.
