The 1972 World Chess Championship in Reykjavik occasioned a fantastic series of caricatures, by Icelandic artist Halldór Pétursson, of Fischer and Spassky. The unwatermarked versions at the bottom of the page are the result of some simple but clever image processing.
Franz Sedlacek (1891 – 1945) was an Austrian painter who belonged to the tradition known as "New Objectivity" ("neue Sachlichkeit"), an artistic movement similar to Magical Realism. At the end of the Second World War he "disappeared" as a soldier of the Wehrmacht somewhere in Poland.
This past Spring, Duke University hosted concurrent exhibits that featured curated images of satirical political cartoons. Fortunately, the exhibits are free to enjoy from the comfort of your bed/couch/desk chair. From the Nasher Museum of Art, there is Lines of Attack: Conflicts in Caricature, comparing pieces from as early as 19th Century France to post 9/11 US. From the Perkins Library, we get Abusing Power: Satirical Journals, an exhibit of 19th and early 20th Century pieces from around the world.
The Hirschfeld Follies: A charming and generous gallery of Al Hirschfeld's portraits from The New York Times, spanning from 1928 to 2002 (registration required), indexed by date, person and show.

[Be sure to accompany with plep's great post on American cartoon and caricature and PeteyStock's January 2004 obituary post. And while you're at it, if you'll excuse the immodesty, my own David Levine post, with a (superb) still-working link.]
