 Or Superman himself, complete to flying red cape and Superman insignia. What's more, it's easy as anything to collect these Pep comic buttons. You don't have to send in any money, not even a box top. And you can't buy them anywhere. But you'll find a comic button in every package of Kellogg's Pep you open. And you'll find yourself a load of good eating in a package of Pep, too. A bowl of these crisp toasted whole wheat flakes is just the thing to wake up your appetite on a chilly morning.
