This paper examines the work of Swedish comics creator Simon Gardenfors, Simons 120 dagar, as an example of autobiographical comic art in which the concepts of performance and performativity, as developed by Erika Fischer-Lichte, are applied to explore aspects of self-construction. It discusses Gardenfors' performative action as a means of extracting experiences with the intention of making artistic work. Self-construction is shaped in relation to the participants in the art project. The work is the product of a social project, but also in relation to elements staged before the advent of the work. By exploring how Gardenfors' idea was enunciated and what it achieved, we can examine how he stretches compositional limits and how his graphic memoir becomes a part of a larger artistic event. By working as a performance artist during his production of the book, and by commenting and sometimes interacting with his readers in blog form before, during and after, Gardenfors' work attains a performative dimension.
