In a world inundated with photo upon photo upon video upon photo, sometimes something as simple as an illustration can stop a viewer in their tracks.
More and more publications, like Port magazine, have incorporated illustrations as a regular component to their pages. And popular children's books also are heavy with a very specific sketch technique, like Miroslav Sasek's This is.. (London, New York, Paris) series. In short, the softer image choice that can be found in an illustration is something to be considered when developing new marketing material. Keep an eye out for them.
