Conceptual metaphor theory/CMT (fathered by Lakoff and Johnson's Metaphors We Live By, 1980) claims that human beings do not only speak and write, but actually THINK metaphorically. Within CMT this is mainly demonstrated on the basis of verbal communication. In order to substantiate CMT's claims, it is necessary to show that, and how, conceptual metaphors also standardly appear in non-verbal discourses, for instance in comics. In turn, visual studies and comics scholarship may benefit from such investigations. It is argued that (i) the representations of anger found here are, at the least, compatible with the most dominant anger metaphor found by Kovecses, namely ANGER IS THE HEAT OF A FLUID IN A CONTAINER, and are probably motivated by it; and (ii) the medium of comics may privilege aspects of ICMs that are less dominant, or even absent, in its linguistic manifestations.
