German Empire - Zeppelin mail Graf Zeppelin 1931

A very special postcard from 1931 that was addressed to Heinrich Kubis, who was employed on this airship Graf Zeppelin as a steward and who, many years later, continued in the same role on the Hindenburg.
During the fire on the LZ129, on May 6, 1937, he helped many passengers evacuate the ship and himself survived the disaster as one of the 62 in Lakehurst, New Jersey.
