Jérôme-Martin Langlois (Paris, March 11, 1779 - Paris, December 28, 1838), "Portrait of the Comte de M.", 1831

One of my favorite paintings at the Portland Art Museum.  The subject has such character; his smiling eyes and the way his lower lip tucks in under the upper is so charming, touching somehow.  And he looks ready to speak to the viewer - the voice would be basso, certainly, with a rumbling, rolling French.
