One of our favorites is Christmas at Ground Zero by "Weird" Al Yankovic.
(You were expecting maybe Adeste Fidelis?)
Within our sci-fi-oriented The Future WAS Fantastic!™ section is the Atomic War line of kool collectibles with classic comic book covers from the fear-filled '50s, featuring the nuclear destruction of New York City (see above), Washington DC, and Moscow on black hoodies, sweats, and tees, as well as mugs and other tchochkies!
So for all you survivalists out there, while you duck n' cover under the Christmas tree, prepare for the irradiated end stylishly with our radiation-proof (not really!) garb and goodies!
