Eclipse!

The Great American Eclipse is today!

The USPS issued a commemorative stamp (in June, on the summer solstice) to celebrate this rare event.

These stamps use a special ink that is black when cool, showing a total solar eclipse. The ink fades when heated by your breath or finger to reveal the moon!

You can buy them here. The back of the stamp sheet provides a map of the path of totality:

You can learn more about the stamps and their special ink here.

Post offices in the path of the eclipse are offering special pictorial cancellations until September.  You can find a post office and request these special cancellations here.

If you have never requested special postmarks, here are some great instructions to get a pristine example back!

Here are a couple of examples of pictorial cancellations:

Most of the U.S. will see at least a partial eclipse today, so be safe in your viewing. If you would rather just watch the total eclipse online, you can find some options here.

And I recommend you check out this TED video. It’s incredible!!
