total eclipse stamps

[asakiyume]

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.

It's a fun, inventive thing to do. Good on the post office for trying to find new ways to make people care about stamps, you know?
