Election posters are a visual means of communicating political messages to a large audience, and they are an important print medium for political communication that is directly controlled by political actors. Posters have played a large role in election campaigns for the past two centuries, and as a result, this trend continues in many countries today. The legacy of socialism and the rule of the Communist Party made posters even more important in Slovenia, due to the medium’s significant function in the propaganda machinery. By employing the informative-persuasive framework, we analysed the nature of electoral competition in Slovenian poster campaigning as well as the extent of its (dis)continuity with posters from the period of communist monism. Based on the content analysis of posters from the communist and non-communist periods, we observed that Slovenian posters in the post-1991 democratic era reflect patterns of poster campaigning characteristic of liberal democracies and demonstrate a clear break with posters from the communist regime. Those patterns confirm the general assumption that dominant political actors employ more persuasive poster campaigning, while the less established devote more attention to informative activities.
