This is a mint 2016 USPS stamp sheet of 16 self adhesive FOREVER stamps: Total Eclipse of the Sun to commemorate the upcoming August 21, 2017 eclipse as it sweeps a narrow path across the entire country, the first time since 1918. This is the first U.S. stamp to use thermochromic ink which reacts to the heat of your touch. Placing your finger over the black disc on the stamp causes the ink to change from black to clear to reveal an underlying image of the moon. The image reverts back to the black disc once it cools. The back of the stamp pane shows a map of the eclipse patch. Measures 6-1/4" x 6-1/4" . Mint condition. Shipping is $2.95 within the USA. International shipping rates apply.
