The LZ 129 Hindenburg was a German commercial passenger-carrying rigid airship, the lead ship of the Hindenburg class, and the largest dirigible ever built. During its inaugural 1936 season, the airship inaugurated the first regular transatlantic passenger and mail service between Frankfurt, Germany, and the Naval Air Station at Lakehurst, New Jersey. This cover specifically commemorates the 40th anniversary of Flight No. 10 from that highly successful first season, marking a pinnacle of commercial lighter-than-air aviation before the ship's tragic loss in May 1937.
This is a neat, well-preserved piece for collectors of zeppelin postal history, aviation topicals, or Zaso silk cachets.
