Punch's Fancy Portraits = witty Victorian cartoons appearing in "Punch", a British satirical magazine (1841-1992, 1996-2002). One example in Volume 80, 19 March 1881, p.130, is of Thomas Henry Huxley (1825-1895), who was Inspector of Fisheries, but more famously known as "Darwin's bulldog" for his defense of  Darwin's theory of evolution.
