This video from MOCAtv is a must-see. Mujeres Creando are a Bolivian collective who have been promoting anarcho-feminist messages through protests, street interventions, graffiti and much more for over twenty years. Very powerful and inspiring stuff.
It seems worth noting the similarities between Mujeres Creando’s graffiti and Situationist International’s graffiti, if only to point out that there is a history of political graffiti as art, but of course it’s also an interesting connection because so much contemporary street art can be traced back to the ideas of Guy Debord and Situationist International.
