So much for the front pages of old comic books

In the back pages you'd find mostly dubious ads for impossibly cheap, impossibly cool novelties and "easy" moneymaking "opportunities."

Though this one is from the '50s, ads just like it were still running in Kelly's childhood. And $50 was still a lot of money then.

The Cussans' business was much more small time and less legal, and they could only dream of running a full-page ad like this.
