<p>If you asked me to list the three greatest cartoonists from a century ago, the first two would be easy: No. 1, George Herriman, whose "Krazy Kat" created a surreal world around the love triangle of the titular, gender-fluid feline, her — or, sometimes, his — unrequited love for the brick-throwing Ignatz Mouse, both kept in line by Krazy's secret admirer, Offissa Pupp, all capering across a stark Arizona scrubland conjured up by Herriman's madly creative pen.</p><p>Then Windsor McKay, whose "Little Nemo in Slumberland" plunged readers into Art Nouveau dreamscape where a little boy peers over pillows while his bed, its legs impossible long, strides down Fifth Avenue.</p><p>As for the third, I'd be hard-pressed. But Rube Goldberg would certainly qualify.
