"The Inverted Jenny (also known as an Upside Down Jenny or Jenny Invert) is a United States postage stamp first issued on May 10, 1918 in which the image of the Curtiss JN-4 airplane in the center of the design was accidentally printed upside-down; it is probably the most famous error in American philately. Only one pane of 100 of the invert stamps was ever found, making this error one of the most prized in all philately; an inverted Jenny was sold at a Robert A. Siegel auction in November 2007 for US $977,500.[1]"

A meticulous and shameless counterfeiting of a pane of the priceless stamps, done in an edition of 30.
