 Of course, Superman's an old favorite with his bright blue jersey and his Superman insignia. And remember, these pet comic buttons are done up in full color. Sure, they show up like anything when you wear them pinned on your jacket or your dresser cap. So hop to it, gang. Ask Mom to get you another box or two of Kellogg's Pet. That's the only way you can get these comic buttons, you know. You don't send in any money, not even a box stop. And you can't buy them anywhere.
