DONNELLY/COLT BUTTONS BOX 188 HAMPTON CT 06247
This button was likely worn by anti-nuclear protesters following the Three Miles Island meltdown, which killed many cows. This nuclear meltdown occurred on March 28, 1979, in Pennsylvania, United States. It was considered the worst accident in U.S. nuclear power plant history. After the meltdown, an estimated 65,000 people attended a march and rally against nuclear power. For months more would join the rallies and march all across the country. The cow on the button represents the cows that were poisoned and killed due to the meltdown.
