This beautiful pink cover was custom made for Dr. Marvin Speer, a House of Farnam collecting specialist. He contracted with Mike Zoeller at Artmaster (who now makes Farnam) to make this HF variety for the Breast Cancer Research stamp, that consisted of the normal HF cachet on a pink envelope with a DC slogan cancellation. The good doctor created this special edition to surprise and support his wife who is an active volunteer in support of breast cancer treatment and cure.
Leroy B. Jahn, inventor of a parachute device for dropping objects from planes without landing, interested the Post Office Department in his device and secured special permission to have pilot Walter H. Stevens of the Air Mail Service fly a mail plane over the Capitol grounds. The flight occurred on December 5, 1919. One hundred and thirty-four covers, prepared by a Washington, DC, philatelist, were dropped, as were packages of eggs and other items.
This cover is one of only a few items dispatched from Austria and flown by the LZ127 Graf Zeppelin from Friedrichshafen on the Orient flight and dropped over Er Ramle. The red flight cachet of the zeppelin flying over the pyramids is the variety produced with steel cachet rather than a rubber cachet. The destination is of special interest since not much mail was addressed to Palestine.
