I wanted to upload my LZ130 Graf Zeppelin II cover a long time back but could not do so... here it is for you all to see.
This is the Flight 8 - Sudetenlandfahrt of the 30 or so flights made. This was the last of the of Zeppelins.
It features the 1938 set of stamps showing Austrian landscapes and different native flowers. This cover was dropped in Reichenberg on December 2, 1938 during flight over Sudetenland.
Catalog reference Sieger 456.
