EXTREMELY FINE BLOCK. A SUPERB AND RARE BLOCK OF THE ONE-CENT PAN-AMERICAN INVERT -- WONDERFUL CENTERING AND FRESHNESS.

The Pan-American inverts were the first bicolored postage stamps produced by the Bureau of Engraving and Printing and the first invert postage errors issued by the Post Office since the 1869's. The 1c Pan American Inverts were found in several post offices around the country. Thirteen blocks of four, a block of six and a block of 20 are recorded in our Levi records, some of which may have been broken into singles.

VERY FINE EXAMPLE OF THE 4-CENT PAN-AMERICAN INVERT WITH SPECIMEN OVERPRINT -- AN EXCEEDINGLY RARE STAMP IN SOUND WELL-CENTERED CONDITION.

If the reported numbers are correct, a total of 203 4c Inverts was released, both with and without the overprint. An unknown quantity of the 4c Pan-American invert was overprinted with a small "Specimen" overprint. Some examples, both with and without the overprint, were given away by Third Asst. Postmaster General Edwin C. Madden. When postal authorities learned of the practice, they destroyed 194 copies and put one pane of 100 into the official archives. At a later date, 97 of these were later traded for rarities missing from the archives.
