These cartoons were published on September 8, 11 and 12 1906 in the LA Examiner. Herriman here is pretty much beating the same drum every day, likening candidate Gillett to a mule at the beck and call of the Southern Pacific Railroad.
Since I haven’t much commentary on these ‘toons, I’ll take this Saturday morn to mention Herriman’s art style. Previous to 1906 Garge’s artwork was far, far rougher than the polished stuff you see here (here’s an example). Based on the style, and his known friendship with Tad Dorgan, I think I can safely say that Tad took Herriman under his wing and gave him some pretty intensive art lessons. In fact, if we look at Tad’s work of this time next to Herriman’s they’re hard to tell apart. To compare, check out the June 20 post on Eddie Campbell’s blog.
