USPS Total Solar Eclipse Stamp

The images above show the Forever stamp that will be issued in honor of the eclipse by the U.S. Postal Service. The USPS will issue a first-of-its-kind heat-sensitive stamp that changes when touched. The first day of issue will be June 20, 2017 (the day of the summer solstice). Stamps can also be pre-ordered in early June from usps.com/shop. Images courtesy of the U.S. Postal Service.
