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.
