I've been slack in posting these vitally irrelevant spot illustrations, so here's one from the Washington Post Magazine of about 13 years ago. The story accompanying the drawing dealt somehow with alcohol in politics and these two, Grover Cleveland and Calvin Coolidge, represented two extremes on the drinking-alcohol spectrum; most bibulous and most teetotal respectively.
I'm pretty sure I stole Coolidge's head shape from a caricature by the spectacular Miguel Covarrubias, though it does have a proto-Peteyness feel that creeps me out some. And the handling of the watercolor is kind of soft and timid. But I do like the looks of mutual disgust that flash between the former presidents.
