Visual art is political and this role is even stronger when it is displayed as an act of political disruption. During crises, the walls on urban streets become canvases visible to everyone. The impact of having a mass audience is constrained, however, by the need for legal authorization.

Moreover, Argentinean street art represents a new alternative channel for the application of free speech.
