The concept of what boyhood is is developed through Tom's actions as well as his runaway adventure with Joe and Huckleberry. To help show how mischievous and messy boyhood was, The Miriam and Ira D. Wallach Division of Art, Prints and Photographs, shows a picture of a young boy smoking a pipe, sawing furniture, climbing all over the place, and sleeping. In Twain's novel, Tom and his friend are young when they decide they want to learn how to smoke a pipe.
