I read
Plakat aus den Parteikämpfen im Kansasgebiete
which I would translate to
Poster from the party struggles in the Kansas area.
Another translation, suggested by guidot in the comment, is
Poster from the election campaign in the Kansas area.
The word Parteikampf is not longer used in current German. Translating it as "party struggle" draws an analogy from Klassenkampf ("class struggle"), while "election campaign" draws the analogy to "ahlkampfWahlkampf" ("election campaign", literally).
