Shipping was set at 24c and the two-color stamp was available since the day before. The blue center displays the biplane model selected for this service, a Jenny, nickname for the Curtiss JN-4. The preparation of the stamp was made in a hurry. The die for printing the plane had been completed only six days earlier. The engraver added in the picture the serial number of the aircraft scheduled for the official inaugural flight, 38262.
We are still in the heroic time of aviation. The President is upset : he is wasting his precious time. 38262 takes off southward instead of going toward Philadelphia. The pilot tried to land in the countryside and bogged down in a swamp this plane carrying the first mailbag of the new service. Fortunately in the opposite way on the same day the first north-south transfer is successful.
Philatelists rushed. One of them acquired for $ 24 a complete sheet of 100 stamps in which the blue print of the image is inverted by reference with its rose carmine frame. He does not know it yet : this error is unique.
The pieces from this Inverted Jenny sheet were dispersed shortly afterwards. Two of them can be rightly considered as the gems of US philately.
