The Lady Liberty forever coil stamp issued in December 2010.
How fantastically hyperreal: Turns out the United States Postal Service's brand new Statue of Liberty stamp, seen below, accidentally features an illustration of the Lady Liberty replica at Las Vegas's New York-New York casino as opposed to the real statue in New York Harbor.
The replica statue in Las Vegas (left) and the real Statue of Liberty in New York (right). The lighter rectangular patch in the center crown spike on the replica appears on the stamp. The actual statue does not have this feature.
A philatelist and fan of the NYC statue noticed the error and informed Linn's Stamp News. They investigated and published the above comparative photos, with the replica at top left.
