fallout shelter sign
Atomic bunker indicator
A fallout shelter sign is the distinctive black-and-yellow placard marking buildings designated as public refuges during nuclear attack.
The signs, featuring a radiation symbol and capacity number, were posted on thousands of American buildings during the Cold War as part of civil defense planning.
Many remain visible today as artifacts of midcentury nuclear anxiety.
