This is an excellent empty (but opened) 4-7/8 x 6-1/8 inch special philatelic envelope mailed from the United States to Germany in October 1928 aboard the famous German airship LZ127 "Graf Zeppelin" by Air Mail.

Beneath the lower Washington DC cancelations on the front of the envelope are two 20 cent and one 5 cent US Air Mail stamps, and the stamps in the upper right corner are 10 and 50 cent US stamps.

Across the Mail-To address is a large purple stamp that says FIRST FLIGHT AIR MAIL VIA GRAF ZEPPELIN UNITED STATES - GERMANY OCTOBER 28 1918. On the back side is the arrival cancelation at Friedrichshafen-Bodensee dated 1 November 1928. In the upper right corner of the front side and the lower right corner of the back side is a special, very rare German postal label saying that the envelope was damaged in transit, something no German would want to admit.

This envelope was mailed by an employee of the Austrian Embassy in Washington DC.
