A series of pencil drawings on white paper depict a character transforming from a smiling man in a cap to a man with glasses drinking from a mug, then to a muscular bodybuilder, followed by a woman whispering to a surprised woman, then to a man in a suit adjusting his jacket, and finally back to the smiling man in the cap. The drawings are shown in a sequence, each appearing as a new image on the paper.
