The following thesis is a visual semiotic analysis of posters used by Swedish political parties during the election campaigns of two elections to the Swedish Riksdag, 1979 and 2014. Semiotic theories and concepts are utilized in order to explore if and how the usage of images in these posters has changed between 1979 and 2014. The parties were found to have more heavily emphasized clarity in communication in 2014 than in 1979 through a heavier use of photographic images. Further, the parties were found to subvert or downplay elements of their own images in 2014, while no such attempts were made in 1979.
