Propaganda
Dreyfus himself was often portrayed by anti-Dreyfusards as conniving and sub-human. Zola was characterized in an equally unflattering manner. The poster series Musée des Horreurs (Museum of Horrors, or Freak Show) and Musée des Patriotes (Museum of Patriots), created by an anti-Dreyfusard cartoonist beginning in 1899, illustrate some of the ways in which those who were pro- or anti-Dreyfus were portrayed. The Musée des Horreurs dehumanizes Dreyfus supporters, portraying them as grotesque and animal-like. Even government officials were subject to vilification. The Musée des Patriotes glorifies those who were against Dreyfus.
Pro-Dreyfusard propaganda existed as well; one print of a series published to support the cause of Georges Picquart depicts the voice of justice and truth crying out and being harshly muffled by a fist. A postcard depicting the antisemitic journalist Drumont as a beast with fangs may have been sent by a Dreyfus supporter in 1905: writing on the card states, “I am a little tired of this nightmare.”
