How did posters and graffiti become important forms of expression during May 1968?

During the student revolt of May 1968 in France, posters and graffiti emerged as essential instruments of subversion. As activists sought to challenge the established social order, these mediums were elevated to a form of popular art.1

This creative expression was part of a broader, spontaneous performance across streets, factories, and universities aimed at subverting bourgeois culture. By utilizing these visual tools, participants moved beyond traditional political discourse to critique the "everyday life" and ideological coercion inherent in a modern consumer society. This shift allowed the "sixty-eighters" to address qualitative issues—such as social control and the quality of lived experience—that transcended the narrow economic focus of orthodox political movements. Ultimately, these posters and graffiti became iconic symbols of the era, reflecting a desire for social emancipation and a rejection of the status quo.12
