Hello,
I agree with Rammjäger.
Apart from that terrible use of the German Language, which does not speak for a German publishing company, I would very much like to know how a image of Fokker Dr.I 425/17 (that red little triplane) could be linked to a date as early as September 1917.
This is definetely a fake.
If it is vintage, it is certainly not printed by a German publisher like "Schlüssel Verlag", and most probably was printed after the death of
Manfred von Richthofen.
Also note the use of the supposedly old German font style. Does anybody know of any original document printed during WWI that actually used that type of font?
Regarding the grammer: "Hier sind geschildert...." is obviously an attempt to translate "Here are depicted..." into German. The correct translation would read "Hier sind abgebildet....".
It is a funny thing with far too many obvious mistakes to be considered a vintage German document.
As I said: If it is vinatge it was created by a non German after WWI.
Cheers!
Achim
