The goal of this chapter is to outline a theory of punk culture and its constituting principles that allow us to individuate punk comics. We focus on one specific aspect: the “Do It Yourself” (henceforth DYI) philosophy, usually defined as the desire to modify and design objects, possessions and parts of the environment (Wolf and McQuitty 1-2). Although certainly not specific to the punk movement, this philosophy played a key role in the evolution of punk culture. With respect to its use in comics, we address a central question about the role of this philosophy/principle: whether and how the DYI philosophy, acting as a core principle of punk culture, can crucially individuate “punk comics.” The chapter is organized as follows. Section 2 introduces core theoretical notions. Section 3 presents a discussion of comics that acted as “precursors” to the genre. Section 4 presents a discussion of punk comics, while section 5 discusses “contemporary” works in this genre. Section 6 concludes.
