In a cartoon, what do you call the sweat drops shooting off a character’s head? Those are “Plewds.” What about when you see a character wagging their tongue out of their mouth? Oh, that’s a “Protusilation.” How about the lines coming off a freshly baked pie? That’s “Waftarom.” This sort of playful comics nomenclature abounds in The Lexicon of Comicana, the revered 1980 cartooning handbook authored by Mort Walker, creator of the legendary daily comic strip Beetle Bailey.

Both a send-up of lofty how-to-draw books and a sincere and hilarious love letter to the art of drawing cartoons, the Lexicon is a joyously exhaustive cheat sheet to key comics visuals that has been referenced and treasured by generations of cartoonists. This new edition includes an introduction by Chris Ware—who keeps a copy of the Lexicon next to his desk—and a meticulous appendix by Mort’s son Brian Walker, who delves deep into the visual language of comics.

With the help of The Lexicon of Comicana, you’ll come away a better, wiser, richer, and funnier artist. Plus, you’ll learn what a “Morf” is—Mort’s favorite part.
