One of the Legendary Comic Books of the Silver Age featured a cameo by President John F. Kennedy. Part of its legend comes from the fact that it hit the newsstands just a week after JFK was assassinated.
The comic was already at the printers when the assassination occurred and it was too late for the company to cancel the issue. They were afraid the public would consider the comic to be in bad taste under the circumstances. I don't know if they did, but in retrospect, the issue is a quirky piece of comics history, as well as a sad commentary on how times have changed.
It starts off as a typical Silver Age Superman story. Superman is expected to attend a public ceremony in his honor. All in the line of duty for a hero as beloved as Superman. The problem is that Clark Kent has been selected as one of the people to share the stage with him.
Now normally this would be no biggie; Superman would just use one of his robot duplicates to impersonate him or maybe ask his buddy Bruce Wayne to pose as Clark Kent. Except that Batman is also supposed to be at the event honoring him; and Lois Lane has set up metal detectors at all the entrances to the hall as one of her wacky schemes to prove that Clark is really Superman. Dang that woman!
So what's a Man of Steel to do?
The story leaves the reader in suspense until the very last page. Superman appears at the event, and shakes the hands of both Batman and Clark Kent. Lois fails to detect any robot impostors. How did Superman pull it off?
At the very end we see Superman going to thank his secret accomplice who helped by posing as Clark: John F. Kennedy.
"I knew I wasn't risking my secret identity with you ! After all, if I can't trust the President of the United States, who can I trust?"
Comics guru Tony Isabella has cited this issue as his standard for a good president. A good president, he says, is one to whom Superman can confidently divulge his Secret Identity. Sadly, we have had very few in my lifetime whom I think Superman could trust.
