The human in the picture is incomplete, as seen by the darker half. Upon printing, the values would switch, resulting in the black half becoming white. This reversal added a feeling of emptiness that needed to be filled by the viewers mind. The flame pattern in the background is a representation of the artists rage, due to the design being broken and disjointed. The two scale changes are both to exaggerate how the artist became the subject of his own work, and how the large pencil is actively in use to balance the composition.
