Hello,

This are very nice covers of the famous Zeppelin era in Germany during the 1930 years.

Collectors from all over the world could post letters from their countries to be sent with Zeppelin flights. The postage for the Zeppelin flights starting in Friedrichshafen (Lake Constance) was paid with German stamps and the postage from their countries to Friedrichshafen with their own stamps.

I cannot tell you the value of these covers but special catalogues exist for Zeppelin flights.

Best regards
Baber
