Cover sent via Graf Zeppelin from Cardington to Charlottenburg (Berlin). Come swith accompanying letter saying this indeed was given to the Airship [on its stop] in Cardington, but the office there did not accept mail for the flight therefore could not carry the official cachet. "Die uns mit Schreiben uebersandten 2 Postkarten und 2 Briefe wurden zwar dem Luftschiff in Cardington mitgegeben, jedoch nicht vom Amts wegen befoerdert" A rare combination.
