A 1st-of-its-kind stamp that changes when you touch it, commemorating the August 21, 2017 total solar eclipse. Fred Espenak – whose photos are on the new stamp – tells the story.
The Total Eclipse of the Sun, Forever® stamp transforms into an image of the Moon from the heat of a finger. Espenak shot the eclipse photo from Jalu, Libya in 2006, while the Full Moon image was made from his observatory in Portal, Arizona in 2010. The stamp commemorates the total solar eclipse of August 21, 2017 that crosses the USA.
