German Zeppelin Real Photo RPPC franked with Swiss stamps flown on the Graf Zeppelin LZ127 airship's 1932 Danzig LUPOSTA return flight. Top condition, as per scans. '17 CV EUR150. This is from the estate of the nephew of Oberingenieur Karl Beuerle, a lead mechanic on the Zeppelin. A long-time airman, having survived serving in various WWI Zeppelin airships, he was with the Graf from the start (we have several pioneer usages as well!). We were lucky enough to purchase the entire Zeppelin collection of the nephew, who took all of "Onkel Karl's" correspondence and added to it with many further flights. This cover is from Karl himself to his friend Gottfried Braun in Esslingen, and signed "Beste Gruesse, Karl." A rare opportunity - a Swiss treaty sent by a crewman!
