EXTREMELY FINE AND CHOICE. A PRISTINE EXAMPLE OF THIS POPULAR MODERN ERROR.
Popularly called the "C.I.A. Invert", a single pane of 100 stamps was purchased at a the McLean Va. Post Office by employees of the C.I.A., for use on mail from the agency. After using five stamps, they noticed the error, pooled together funds to buy a replacement sheet and kept the rest of the pane for themselves. When it was discovered who had purchased the stamps, a scandal ensued over who actually owned the stamps.
EXTREMELY FINE. THIS EXCITING NEW DISCOVERY IS THE ONLY PANE KNOWN OF THIS MAJOR ERROR.
Perhaps one reason this remained undiscovered for thirteen years is the subtlety of the missing colors -- the black on the Capitol, covered wagon and globe, and the red on the shoe.
