This set of five postage stamps comes from the 1978 Luftpostausstellung Stuttgart. Four postage stamps celebrate early German aviation. They are in four different denominations. The largest is for the Graf Zeppelin. All have been hand canceled in Berlin for collectors. The group’s fifth piece is a special stamp on a card with the name Luftpostausstellung Stuttgart from 1978. It displays a stamp commemorating aviation in Germany. It is a very handsome set.
