Tucked into a dark and tiny corner of the PMA showfloor is a revolution made by a small Korean company called Wooyoun: metal photographs that last for 20,000 years. These images depicting the Democratic US presidential frontrunners (and no Republicans) were chemically etched in a patented, print-like process—probably with stuff that gives improperly masked technicians some horribly debilitating ailment. They'll last up to 1,000 years under the hot unforgiving sun. Hear that? Screw biodegradability. Put another way, that Hillary card you see in the gallery will outlast her reign by at least 15,000 years.
