Punk was visual as much as it was musical. In recent years, art historical research of punk works of art has increased. However, a thorough analysis of punk art's themes, motifs, and methods is still lacking. This article examines infantilism and dilettantism as two key notions within punk art, as illustrated by the collage L'ecole de l'art infantile (COUM Transmissions, 1974) and the super 8 film Das Leben des Sid Vicious (Die Tödliche Doris, 1981). Analysis shows how concepts of childishness, nonconformism and anti-authoritarianism are interconnected both with punk's DIY ethos and its self-identification as a youth movement. Furthermore, the article discusses punk art's circumvention of antithetical concepts, such as failure vs. success, innocence vs. guilt, reality vs. fantasy, skill vs. incompetence.
