 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.
