The US Postal Service will release a new, unique stamp that transforms when you touch it in honor of the first US total solar eclipse since 1979 approaching this summer!
The total solar eclipse stamp will be printed with thermochromic ink so that when you rub it, the image of a blacked-out sun transforms into a detailed photo of the moon that’s blocking it.The “forever” stamp will be sold starting June 20, with an option to buy an envelope to protect it from UV light. The back sheet of the stamps will feature a map showing the path of the eclipse across the United States on Aug. 21.
The USPS revealed what the stamp will loo like, before and after you touch it:
