ABSTRACT
In re-reading the Great War posters according to the principles of modern persuasion, we believe we have succeeded in providing an interpretation of them and an organization useful in defining the strategy of the propagandists. The success of the subjects and the effectiveness of the persuasive techniques used to create poster campaigns which were carried out to induce agreement and modify attitudes, was incontestable. On the American side, the army numbered no more than 200,000 men at first, but in the end it was composed of more than 4 million people who had allowed themselves to be persuaded to leave for the distant, and for the greater part of them, unknown, overseas countries. In the US they involved the home front in the production of armaments and food to send to the soldiers and to serve to those at home.
