Total solar eclipse stamps change to moon from heat of fingers
DENVER -- Finally, a postage stamp fit for the 1980s angst of singer Bonnie Tyler and her broken-hearted ballad, "Total Eclipse of the Heart." Only, in this case, it's a total eclipse of the sun -- with just the touch of a finger. The stamp changes from an image of the total eclipse into the moon from the heat of a finger. Once cooled, the image returns to that of the total eclipse.
