Translated into English for the first time from material provided by airship historian Hendrick Stoops, this short booklet was originally produced in 1930 to celebrate 30 years of Zeppelin flight. It contains a brief history of the early Zeppelins and DELAG ships, a description of the LZ 127 'Graf Zeppelin', an account of the Round the World Flight, and tables showing the flights of the LZ 127 to date.
