USPS issues special commemorative solar eclipse stamp

Tom Hinde

Eclipse mania has arrived at the U.S. Postal Service (USPS). USPS issued a special "forever" stamp to commemorate the first coast-to-coast total solar eclipse in America since 1918. The first of its kind stamp uses thermochromic ink. The stamp transforms from a blocked-out sun to a full moon by the heat of a finger.

The total solar eclipse is August 21. It will be visible in 14 states, from Oregon to South Carolina, but nowhere in Texas.
