FRESH AND FINE ORIGINAL-GUM EXAMPLE OF THE ONE-CENT PAN-AMERICAN INVERT.
According to Johl, the 1c Pan-American Inverts were found in at least four different post offices around the country soon after release of the issue in May 1901, including Bessemer Ala., Richmond Va., Utica N.Y. and Connecticut. Most examples are off-center and/or have disturbed gum.

EXTREMELY FINE APPEARING EXAMPLE OF THE 4-CENT PAN-AMERICAN INVERT.
The 4c Pan-American Invert was a special printing and not regularly issued. Examples were distributed through two official channels, and the gum on the majority of stamps without "Specimen" overprint was disturbed. In fact, because the stamps were removed from mounting paper, they are generally thinned or have seriously disturbed gum.
