Bodensee 1919 missed flight from Friedrichshafen to Berlin
This cover, dispatched from Friedrichshafen on November 21, 1919, was intended for LZ 120 Bodensee flight from Friedrichshafen to Berlin. However, it went by surface mail since there was no zeppelin flight to Berlin until November 23. The blue Friedrichshafen cachet (usually in red) confirms that the cover went by surface when the flight was cancelled. The Friedrichshafen postmark shows the incorrect date of November 31 instead of November 21.
