New York City has started taking down the yellow nuclear fallout shelter signs slapped on thousands of buildings across the city in the 1960s. According to AM New York, city officials believe these metal black-and-yellow signs "are misleading Cold War relics that no longer denote functional shelters."

Kennedy created a shelter program in 1961 across U.S. cities as anxieties grew high over the nuclear arms race between the United States and the former Soviet Union. By 1963, an estimated 18,000 shelters had been designated across the five boroughs, and the Department of Defense had plans to add another 34,000 shelters citywide. Most were no more than basements marked by an official government sign--and now the remnants of such signs are coming down.
