IN CASE OF NUCLEAR WAR, RUN TO THE CLOSEST TOURIST CAVE

I only have two of these, but I think they're amazing artifacts from the cold war era.

Can you imagine if an atomic attack had occurred? "Honey, don't forget our Atomic Bomb pass for the cave." Caves were always listed as fallout shelters and I'm sure most of the town would have flocked to one of these caves. I can picture it now. A teen-age tour guide stands in front of the cave checking for Atomic Bomb passes. "Sorry, sir, but you don't have a pass. Next."
