Howdy, folks! It's the last triple-date of the century here on Earth, and the U.S. Postal Service has made available a handful of "12-12-12" pictorial cancellations for those interested in obtaining one. (Of course, you could always get a "DEC 12 2012" postmark anywhere today, but that's not quite the same, is it?) If you're interested in any of these special cancels, please mail the postal card / envelope with the stamp to be cancelled, along with a request to the appropriate postal official, to the address shown at the right. Requests must be received within 30 days. The following information about these commemorative cancels was made available in the most recent Postal Bulletin.
The first commemorative cancels comes courtesy of (what appears to be) the Western Pennsylvania District office, located with the Pittsburgh Main Post Office.
Several post offices in South Dakota are offering 12-12-12 cancels of their own. They're particularly nice as the pictorials present a map of the state with the towns accurately located therein. The instructions for obtaining any of these cancels is the same as above.
I visited one of these offices, that in Buffalo, back in 2008, while heading toward the Geographic Center of the 50 States.

Hope you enjoy!
