By the way, I hate to say it, but poor Perry was one butt-ugly kid. Oh, well, hopefully his mother loved him anyways.
And so Clark Kent joins the Capone mob. To ingratiate himself with Capone, he secretly uses his powers to hijack a beer truck from a rival gang, though he heat-visions the beer to turn it sour so Capone can't profit from the deed.
Capone then orders him to kill a cop. I like the trick he pulls off here: melting the bullets he fires at the cop with heat vision and using super breath to knock his supposed victim unconscious by sucking all the air away. It appears the cop has been shot when he's merely blacked out for a moment.
But the jig is up when Capone hears a radio report that the real "Touch" Vincent is still in prison. Capone figures Clark must be a Fed, prompting the mobsters to try to off him with bullets, knives and a high-voltage power line. But Clark is apparently "Untouchable!"
Clark leaves the story at Perry's shoe shine stand and leaves the 1920s before Eliot Ness can file a law suit for Cool Nickname Infringement.
It's a fun story, written by Otto Binder with the cleverness he always infused into his tales. It probably would have been a lot more fun if young Perry had been more directly involved in getting the story, but the point of the tale is to put Clark and Capone in the same room, so we'll forgive that as well.
But that darn paradox still makes me think. Was Superman (despite being displaced in time) an origianl part of Perry White's history? Did he simply help history along--in which case was anything he did necessary since it presumably would have happened more or less the same way? Did he change history? The last panel has Clark and Perry (back in the present) looking at the framed front page of Perry's first scoop. Was that specific paper always there, or did it fade into something different after Superman altered the time line? Perhaps Perry's first scoop was covering a garbage strike or something like that and Superman changed it into something else.
