SS Liederbuch (5. Auflage), Rasse und Siedlungshauptamt SS, Zentralverlag der NSDAP, Munchen, Full linnen bound. 256 pp.
The original wartime songbook is protected by a plastic bookcover for handling and protecting the cover, and houses in a special professional postwar made collectors slipcase.
The condition is excellent. In my opinion impossible to upgrade.
These booklets have become quite rare to find, and if you find them they almost always have some kind of damage (which is logic judging age and usage).
If you want only one for your collection and in as good as possible condition, then this is the one to get!
