John Heartfield’s photomontages are so powerful they are scary.
The display in room 5 of the Poetry and Dream floor at the Tate Modern also includes a copy of John Reed’s 10 Tage with artwork by Heartfield.
Propaganda. Power and Persuasion at the British Library is less emotional. At the beginning it looks like history of propaganda around the world, but then it quickly becomes thematic, with materials from different periods (but especially 21st century) and countries organized around topics, to prove that when the authorities communicate to the crowd, they always have their own agenda.
I found the section about public health hazards particularly interesting. I remember the leaflets about radioactive fallout during the Cold War, or about AIDS in the Nineties, they were so incredibly detailed, they seemed so objective and scientific, yet they were the product of social science theories. At some point I was so concentrated on finding the hidden purpose of contemporary propaganda, I realized I was actually reading the Fire Action sign of the room.
