EXTREMELY FINE. ONLY TWELVE FIRST DAY COVERS ARE KNOWN BEARING A COMPLETE SET OF THE PAN-AMERICAN EXPOSITION SERIES.
In an article in the June 1999 issue of First Days, Alan Berkun records eleven covers bearing complete sets of the Pan-American Issue, including four from District of Columbia (all to Germany), four from Mass., two from New York and one from Seattle (sold in our 2001 Rarities sale). This cover becomes the 12th first day in the census. One other full set is known on cover to Switzerland, originating in New York. The registry numbers are consistent with those of the other covers recorded by Berkun.

VERY FINE 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 due to its removal from mounting paper. In fact, many of these stamps are thinned or have seriously disturbed gum.
Signed "SA" (Spencer Anderson). With 1968 P.F. certificate describing the stamp as "genuine, unused original gum" However, revised Philatelic Foundation policy is to describe slightly disturbed original gum on No. 296a, due to the manner in which they were reportedly found. We must conform to the current P.F. policy, despite the fresh original gum on this stamp.
VERY FINE AND CHOICE EXAMPLE OF THE 4-CENT PAN-AMERICAN INVERT WITH SPECIMEN OVERPRINT.
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 detroyed 194 copies and put one pane of 100 into the official archives. At a later date, 97 of these were traded for rarities missing from the archives.
