00:10Inverted Jenny
00:14The Inverted Jenny is a United States postage stamp,
00:18first issued on May 10, 1918,
00:21in which the image of the Curtis JN-4 airplane
00:24in the center of the design appears upside down.
00:28It is probably the most famous error in American philately.
00:33Only one pane of a hundred of the Inverted Jenny stamps was ever found,
00:38making this error one of the most prized in all philately.
00:42During the 1910s, the United States Post Office
00:46had made a number of experimental trials of carrying mail by air.
00:51These were shown by the first stamp in the world to picture an airplane,
00:55captioned as Aeroplane Carrying Mail,
00:58one of the U.S. Parcel Post Stamps of 1912-13.
01:02The Post Office finally decided to inaugurate regular service on May 15, 1918,
01:10flying between Washington, D.C., Philadelphia, and New York City.
01:14The Post Office set a controversial rate of $0.24 for the service,
01:19much higher than the $0.03 for first-class mail of the time,
01:23and decided to issue a new stamp just for this rate,
01:26patriotically printed in red and blue,
01:29and depicting a Curtis Jenny JN-4HM,
01:32the biplane specially modified for shuttling the mail.
01:36The stamp's designer, Claire Aubrey-Houston,
01:39apparently had trouble procuring a photograph of that modified model.
01:43It was produced by removing the second pilot seat from the JN-4HT
01:47to create space for mail bags and by increasing the fuel capacity.
01:51The job of designing and printing the new stamp was carried out in a great rush.
01:56Engraving began only on May 4th, and the stamp printed on May 10th.
02:01Since the stamp was printed in two colors,
02:04each sheet had to be placed into the flatbed printing press twice,
02:08an error-prone process that resulted in invert errors in stamps of 1869 and 1901,
02:14and at least three misprinted sheets were found during the production process and destroyed.
02:20It is believed that only one misprinted sheet of 100 stamps got through unnoticed,
02:25and stamp collectors have spent the ensuing years trying to find them all.
02:31The Smithsonian's National Postal Museum offers two explanations for how this might have occurred.
02:37Either a sheet of printed frames was placed in the press upside down for the printing of the plane,
02:42or the printing plate used to print the planes was mounted inverted within the printing press.
