U.S. Postal Service to Issue Changeling Total Solar Eclipse Stamps

A mind-bending stamp.

Ready for the Great American Eclipse? If you’re like us, you’ve been planning on where you’ll be meeting totality on August 21st, 2017 for going on a decade now. It’s the big ticket celestial show of 2017 for sure, maybe the decade (we’re assuming, of course, that a killer comet or alien invasion isn’t on tap for our unsuspecting planet in 2018 through 2020).

Just last month, the U.S. Postal Service got in on the act, with the announcement of a release of a Forever Stamp commemorating the total solar eclipse on June 20th. The first-day-of-issue ceremony takes place at the Art Museum in Laramie, Wyoming, which lies on the eclipse path of totality. Ceremony participants will catch a rare spectacle of June 20th, as a sunbeam meets a silver dollar embedded in the museum floor, an event which only occurs during the June summer solstice. We’ll note if they carry the event live.

The eclipse stamps are printed using thermochromic ink, and will change from totality to an image of a Full Moon when heated, say, by the owner’s thumb, then revert to the eclipsed Sun once again upon cooling. The photo depicts the total solar eclipse snapped from Libya on March 29th, 2006 by Fred Espenak.

Here’s a cool idea; mail a letter/postcard to yourself or a friend on August 21st, 2017 for a one of a kind “postal cover” postmarked with the date of the eclipse… maybe this could become a tradition for eclipse-chasers on subsequent expeditions.

This will be an eclipse for the ages for sure… be sure to pre-order your USPS Eclipse Stamps now, they’re sure to sell out quick!

Where will you be on August 21st, 2017? That date isn’t as far away as you think. Just over three and half years from now, a total solar eclipse will span contiguous United States from the Pacific Northwest to the southeastern Atlantic seaboard. This will be the first solar eclipse to grace the lower 48 states since 1979, and the first time totality has crossed any of the 50 states since 1991. [Read more...]
