The LZ 127 Graf Zeppelin was one of the most successful passenger airships in history. In May 1930, the airship undertook a famous triangular flight to the Americas, departing Germany for Brazil, continuing to the United States, and then returning to Europe. This voyage marked a major milestone in early transatlantic commercial aviation and postal history. This 1985 cover was produced for a regional stamp exhibition (Assindia-Tauschtag) in Essen to celebrate the 55th anniversary of that historic achievement.
This unaddressed cover is a neat, flat example for collectors of aviation postal history, zeppelin topicals, or German event covers.
