What is an object, other than hair gel or grease, that represents Ponyboy Curtis from The Outsiders?

An object that could represent Ponyboy is a heart to stand for emotions and feelings. One of the ways that Ponyboy identifies himself and other Greasers is that they are all very emotional. In a conversation he has with Cherry in chapter three, he states that while Socs are aloof and unfeeling, Greasers experience feelings in very strong ways. He says that it is really the depth of emotion and feelings that separate the two groups.

Another object might be a book. Several times throughout the story it is mentioned that Ponyboy likes to read. In chapter three, Ponyboy and Cherry discuss that he likes to read. In the last chapter, it states that he cannot find a book to read anywhere at home because he has read them all repeatedly. Lastly, the story ends with Ponyboy beginning to write the story of what has happened to his friends during the course of the book.
