USPS releasing heat-sensitive eclipse stamps
Elizabeth LaFleurThe United States Postal Service is commemorating the 2017 total solar eclipse with a first of its kind heat-sensitive stamp. The Total Eclipse of the Sun Forever stamps use thermochromic ink which reacts to body heat. An image of the eclipsed sun transforms into a moon when touched by the heat of a finger. The image returns to its original state once it cools.
The stamp was designed to commemorate an Aug. 21 total solar eclipse which will be visible in parts of the country stretching coast-to-coast from Oregon to South Carolina. Tens of millions of people are expected to be in or travel to the line of totality for the spectacle.

Greenville is in the line of totality. Thousands of people have already booked hotel rooms and tickets to eclipse-related events in the Upstate.
The Total Eclipse of the Sun is a Forever stamp. Each stamp costs 49 cents. The stamp is available for purchase in sheets of 16 at usps.com/shop and will be released to post offices across the country following the Wyoming release on June 20.
