This document discusses posters, including their purpose, characteristics, creation, and use. A poster is meant to convey a message publicly through images and text. It should attract attention, communicate information quickly and efficiently, and contain only one main message. Key parts include a caption, picture, suggested action, and logo. Posters work best when using simple and clear designs, color, and large text that can be read from a distance. They are a good way to disseminate information to both literate and non-literate people.
