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 their significant function in the propaganda machinery. By employing the informative-persuasive framework (Mueller and Stratmann 1994), we analyse the nature of electoral competition in Slovenian poster campaigning as well as the extent of (dis)continuity with posters from communist monism. Based on the content analysis of 841 posters from the communist and non-communist period, we observed that Slovenian posters in the 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 the dominant political actors employ more persuasive poster campaigning, while the less established devote more attention to informative activities. However, the use of posters in their full potential remains to be seen.
