Linn’s Stamp News reports that the U.S. $11.75 Earth hologram stamp has been found in a near-eclipse format. Only one of this remarkable error has been reported, advises John Berry.
Another reported error in the U.S. Space Achievement issue concerns the “Exploring the Solar System” sheet featuring five pentagonal stamps, where one (only) fully imperforate sheet has been found.
This postage stamp (left), which pays the rate for an Express Mail package, is the first circular stamp the United States Postal Service has ever issued. It also features the first hologram on a U.S. stamp. The silvery image reveals a rainbow-streaked view of the Earth with North America at the upper left. The planet appears to rotate 25 degrees east and west when the stamp is moved.
