The Lexicon of Comicana is a 1980 book by the American cartoonist Mort Walker. It was intended as a tongue-in-cheek look at the devices that cartoonists utilize in their craft. In it, Walker invented an international set of symbols called symbolia after researching cartoons around the world. In 1964, Walker had written an article called "Let's Get Down to Grawlixes", a satirical piece for the National Cartoonists Society. He used terms such as grawlixes for his own amusement, but they soon began to catch on and acquired an unexpected validity. The Lexicon was written in response to this.
