John Adcock's Yesterday's Papers blog showcases art by cartoonist Gluyas Williams, with links to more. Williams' quiet observational humor and stark line work and black spotting makes for a distinctive look. You've probably seen his work illustrating a Robert Benchley book, or an old gag cartoon of his from The New Yorker. (His 1928 classic was: "The day a cake of soap sank at Procter & Gamble's.")
Mr. Adcock cites that Mr. Willaims also drew a series of newspaper panels, and reproduces a number of them.
