North America flight 1936 - 2nd trip, double postcard with printed stamp to 15 Pfennig (question and answer part) from Witten 14/5/36 with Zeppelin additional postage via Frankfurt and carried by airship to New York and from there to Duluth. Once there, the reply part of the postcard with USA additional postage for the return by registered mail was prepared and also sent accordingly, which proves the AK stamp from Witten from 3.6.36. So that the rare piece was not separated on the way home, the sender in the US has the double card attached to a cut open part of a letter envelope. Highly interesting piece and possibly unique in the present form, winner 410 B, Michel Flugpost Spezial Catalog 14 a
