As I've gained really valuable information from this forum, I'm asking again some advices and information to a question, that even my local philately shop couldn't answer.
Is there a catalogue of the German feldpost during the years 1914 to 1918? I looked the Michel web page and they didn't seem to have a catalogue from those years. Only the WWII feldpost seems to be there.
The philately shop I visited never heard of a catalogue of WWI feldpost, but were almost certain that there should be one, as Germans seems to be printing catalogues from almost every possible and non possible subjects...
