Vested Interests by Garber has proved to be a really helpful resource for the arguments I want to give in my presentation. Other then intellectual content, the images within the book accurately illustrate the notion of gender being performative; a parody, a mimic. Below are some images taken from the book attesting that gender is a set of acts and gestures, as Butler stated.
