Larger size with red indicium for business, smaller size with green indicium for personal letter use. It was first intended to sell these envelopes only through the Philadelphia Post Office rather than regular stamp and envelope distribution channels. Due to outcry the envelopes were eventually made available through the normal distribution channels. However, the envelope order (from an individual or post office) had to say “Centennial” to get these envelopes. Thus, they were less than 10% of 3¢ envelopes distributed during the 6 months of availability.
Envelopes were sold May 10, 1876 to
November 10, 1876

Die Production
Henry Mitchel engraved 10 dies
Hartford Die
Single line under POSTAGE
Two die types are recognized: one with a single line under “POSTAGE” and one with a double line. These are called the Hartford Die (where the contractor manufactured envelopes) and Philadelphia die, though it is thought that both were used at both locations.
Frame at left has the only known wax impression of the die, along with envelop cut squares of dies 71 (red) and Die 72 (green) and centennial medal/token.
Text on plaque in the wooden frame was: The red wax impression of the original die for the centennial envelope engraved by Henry Mitchell of Boston, Massachusetts in 1876.

10. The Centennial Issue Production at Exhibition
Prior to this time envelope top flaps were gummed by hand (envelopes were spread out on a board with half an inch of flap exposed and gum applied with a roller. This resulted in square gum (top). However, a new Wickham envelope machine was demonstrated at the Philadelphia fair that applied gum resulting in the round gum (bottom). Henceforth all envelopes were made this way.

Sholes and Glidden Typewriter
Later Remington
The typewriter was new and was demonstrated at the fair. At first attendees could type a letter (shown left) but this was too slow so Bain developed a form letter and the attendee only addressed it and the envelope. Shown is an envelope with special cancel from the Centennial Fair.

12. Clark’s Centennial Express
Henry Teft Clark operated from a small store near Sidney, NE. He carried freight from the railroad stop at Sidney, NE to Black Hills mining camps. In addition he provided letter pickup and delivery as an express with additional fee for 2 years. This express service was known as Sidney Short Route. Eleven types of franks are recognized, generally only 1 of each is known and all are scarce.

13. Clark’s Centennial Express
Sidney Short Route express letter sent from Deadwood SD to Seth Bullock,(sheriff of Deadwood) while he was visiting his sister in Tecumseh, MI.

14. Samples sent to GPU in Berne (predecessor to UPU)
Postmaster General Marshall Jewell was one of the organizers of General Postal Union (GPU). These envelopes were sent to the GPU in Berne, Switzerland as requested for all countries to have examples of stamps and envelopes for examine to determine counterfeits. The manuscript notation was applied at Berne.

15. Specimen overprints
Specimen overprinted envelopes were produced for distribution to dignitaries at the Philadelphia Fair. Less than 6 are known.

16. Specimen Overprints
The corner handstamp (enlarged) translates “Collection of thee Main Administration.” The envelope was a gift to the Russian representative at the exhibition where a dinner was held honoring Russia’s having helped the North in the Civil War (they sent ships to protect U.S. ports from British).

17. Usages
Less than 10% of envelopes produced during the 6 months of the fair were Centennial envelopes. The upper left is an uncommon example with advertising. The lower left is an unusual use sent to Montreal, Canada and that had a Canadian stamp added for forwarding. The example at right has an office corner card (name of post office with blank for sender’s name) which is scarce since the local post office had to order at least a box of 250 to sell; the envelope was also sent registered.

18. Forgeries
In the late 1800s German forgers produced forgeries of the stamp indicia. With two exceptions, they are known only as cut squares. In addition to engraving differences, they are on wove paper rather than diagonally laid paper as genuine envelopes.

19. Forgeries
Rare strips of 5 of forgeries (two of each known).

20. Forgeries
Only known examples of forged envelopes produced. Note that the envelope at lower right was mailed within France with franking provided by the French stamp.
