A poster or billboard is a board with information (advertising, political, governmental), usually large, placed outdoors and in places of high visibility, such as at the edge of communication routes and at the entrances of localities, In the past, without current technology, the outdoor was one of the first modes of mass dissemination of products, ideas and services.
Through the repetition of the image and its high visibility, it is intended to obtain a great impact and dissemination in society. However, what has been seen, namely in the interior of Portugal, is the abandonment of these structures, leaving only the large support plates in place. The image they now contain is nothing more than the extend of the landscape in which they find themselves.
