extracted text: Printed with a fluorescent chemical, a luminous necktie glows brilliantly in the blackout. After exposure to light, the treated pattern will glow about 20 minutes. In daylight the tie has no unusual markings, but in total darkness an entirely different pattern appears. The same fluorescent chemical has been applied to a new buttonhole decoration.
