Along with the regular issues, the Special Delivery stamps were created as card proofs at the same time. The color for Scott E3 was decreed by the USPOD as a measure to prevent confusion with the one cent Columbian stamp and was issued as part of the Columbian Exposition series of stamps.48 It is sometimes referred to as the sixteenth stamp of the series.
As was the case with the Special Delivery stamps, card proofs for the Postage Due issues were prepared as part of the card proof sets and prepared at the same time as the regular postage issues.
Postage due stamps were required by USPOD order beginning in 1879 to ensure the accountability of monies collected when postage was not prepaid and thus collected when delivered. Prior to the mandatory use of postage due stamps, “…there was nothing, beyond the honesty of the postmaster, to insure its delivery to the government.”49
There are three series, distinguished by color. This first series was printed in brown. Printing is determined by thickness of card. Anyone wishing more information on this is referred to Greg Vaupotic’s article “Thickness of the Cardboard Proofs by Printing” which appeared in the January 2003 issue of the United States Stamp Society journal.
