USA 2017 Total Eclipse of the Sun Stamps Thermochromic printing







Issue date 20 June 2017

The United States Postal Service (USPS) has issued the first U.S. postage stamps commemorating the 2017 total solar eclipse with thermochromic, or color-changing, ink. The stamp features an image of totality, with the moon completely blocking out the sun and appearing as a black disk surrounded by the sun's corona. But if you place your finger — or rub it — on the blacked-out portion of the stamp, the moon will appear.

The Great American total solar eclipse will sweep across the U.S. in a line from Oregon to South Carolina on Aug. 21 as seen on the back of the sheet.
