From time to time, auction houses offer Zeppelin covers from the Belgian Congo. The price paid for such items is generally far higher than similar covers from the Netherlands or even Belgium – the reason being that between 1932 and 1939 only 15 flights carried mail originating from the Congo.

The LZ 127 ‘Graf Zeppelin’ was arguably the most popular and successful of the Zeppelins. The maiden voyage took place 18th September 1928 and the last on the 26th of April 1937, having achieved 590 successful flights.

It has been established that mail from the Belgian Congo and Ruanda-Urundi was carried on five of its flights as listed below.
