The little guy as realist
A tiny nonhuman observer positioned at the margin of a cartoon is a standard vehicle for the "realist" deflation of pretension. In the Yellow Kid and the subsequent cartoons of Outcault and Luks we can see a genealogical relation between this sort of "little guy" figure and the working class urchins of Hogan's Alley.
