The illustration in terms of advertising and packaging illustration has gained in importance over the past 50 years. The picture, which is attached to a text, is intended to illustrate a situation and make it comprehensible. Illustration is used to visualize information in such a way that it is quickly accessible to the viewer and is clearly accessible.

Of great importance are the pictorial designs also with regard to the mediation of moods, which are to be triggered by the advertised product. Through illustrations, the viewer's emotional level can be approached rather than by the processing of classical text content.

Illustrations are also used in film production in order to present results quickly and without great effort. These are usually presented as hand-drawn "Below the Line - Illustrations or Storyboards".

Illustrations make it easier for us to perceive and understand complex processes quickly. They are an ideal visual aid.
