A small slice of anarchist history! This is a poster announcing the 20th Congress of the AIT/IWA (International Workers Association), held in Madrid in 1996. The AIT/IWA is the strongest international current of anarcho-syndicalism and revolutionary unionism, with chapters across Europe and Latin America.
The proceeds of the sales of this poster will go to support the work of Interference Archive.
These posters are almost 25-years-old, and although they are in surprisingly good condition, they show signs of wear. The entire stack was loosely folded in half at some point, so each poster has a light curve line across the center.
