Additional Information

The Smiling Sun is the international symbol of the anti-nuclear power movement.  It was designed by anti-nuclear activists, Anne Lund and Soren Lisberg, for Denmark's OOA (Organization for Information on Atomic Energy) in 1975. Smiling Sun buttons were originally passed out at the May 1st celebration in Arhus Denmark, but soon were used by anti-nuclear activists around the world, with the words "Nuclear Power? No Thanks" translated into over 40 languages. This message was designed to be polite and friendly, but firm, and to encourage dialog.  The sun was chosen as a symbol of hope because it sustains life on earth. The button is yellow because shops in Denmark use black letters on a yellow background for their signs, so Lund and Soren felt it was a welcoming color.
