I thought these stamps were just cool because hey: cool image! Black and eclipse-y. I've received some on letters and I'd recently bought a sheet.

But then
missroserose sent me a letter with this stamp and pointed out THAT IT CHANGES WHEN EXPOSED TO HEAT.
And I tested it, and it's TRUE. if you expose the stamp to heat, the silhouetted moon suddenly becomes pale and reveals all its features. SO COOL.
What a fun thing for the post office to do. Thank you, USPS.
