what is the illustration
Illustration by Jessie Willcox Smith (1863â1935) An illustration is a decoration, interpretation or visual explanation of a text, concept or process, designed for integration in published media, such as posters, flyers, magazines, books, teaching materials, animations, video games and films. The origin of the word âillustrationâ is late Middle English: via Old French from Latin illustratio, from the verb illustrate.
