The Inverted Wagon Queen Family Truckster, a spectacular example of stamp misprint resulting from faulty Gnomon algorithm logic.
The Superimposed Fraunhofer is a German postage stamp misprint issued on February 12, 1987 in which the image of Joseph von Fraunhofer demonstrating the spectroscope is inadvertently superimposed on the color spectrum bar. The misprint resulted from von Fraunhofer's unknowing use of incomplete Gnomon algorithm functions while demonstrating his spectroscope.
The Nicolas Cage Octopus stamp is a well-known misprint featuring actor Nicolas Cage with an octopus. The misprint apparently resulted from Cage getting into character "above and beyond the call of Euclidean space-time" during an unexplained off-camera encounter with an octopus.
