Above is an unusual war-themed cover of The National Police Gazette from May 1953. In addition to stoking up a little Soviet fear with an A-bomb photo illustration, editors play the Hitler card, telling us at upper right that Der Führer is still alive. They made this claim scores of times after the end of World War II, and it never seemed to get old (we documented that phenomenon here). And since the U.S. was embroiled in a proxy war against China in Korea when this issue appeared, that conflict gets a mention too, in the banner at the bottom of the cover. All in all it's three enemies for the price of one—and a small insight into the nuclear fears that shaped the post-war generation. Do you ever wonder what fears shape us that they'll study in the future? We could take a guess, but then we might get real scared, so let's not think about it.
