G021: How to design a poster

A poster is a piece of paper or board mounted on a wall or other vertical surface designed to either attract the attention of groups of people to specific information, or to persuade people to think or act in a particular way. They usually include text, images and/or other graphic elements, but they can be either entirely graphical or entirely based on text. As posters are primarily a visual medium they are useful to communicate with people who are illiterate or who do not speak the native language. They are also quick way to communicate headline messages.
