EXTREMELY FINE EXAMPLE OF THIS RARE COLOR VARIETY.

VERY FINE. THE ONLY RECORDED EXAMPLE OF THIS MAJOR ERROR.
This stamp was issued in 1969, but the error was not discovered until more than 35 years later. It is unusual that a major error is discovered decades later. Therefore, it is quite unlikely that any others will be found. No other errors of any kind of the 6c Football are known

EXTREMELY FINE. A PRISTINE MINT NEVER-HINGED EXAMPLE OF THIS POPULAR MODERN ERROR -- THE C.I.A. INVERT.
Popularly called the "C.I.A. Invert", a single pane of 100 stamps was purchased at the McLean Va. Post Office by employees of the C.I.A., for use on mail from the agency. They noticed the error, pooled together funds to buy a replacement sheet and kept the pane for themselves. When it was discovered who had purchased the stamps, a scandal ensued over who actually owned the stamps. Of the pane of 100, only 93 sound examples reached collectors.
