I love propaganda posters, they play on the most basic of human instincts - hate. Not that I condone hatred.
The way that the simplest of design styles portrays a powerful message which entrances a country or state has always fascinated me. Though the styles vary massively the simplicity always stays. These posters are designed for the lowest common denominator and give people something to rally round, it makes them feel part of a group - protected in their collective hatred of another group. As an artform I'm not certain how beloved it is, such amazing graphics but with a very dark meaning.
The V&A are holding an exhibition Cold War Modern to highlight the works.
