On October 5, 1988, a Chilean national plebiscite was held to determine whether or not Augusto Pinochet would continue as the country’s leader for another eight-year term. The “No” side won with over 55% of the vote, and Pinochet eventually stepped down from office in March of 1990, putting an end to his military dictatorship.
In Mexico, graphic designer Alejandro Magallanes came up last year with the "No more blood" campaign, as I mentioned before. The logo looks quite similar. Coincidence or inspiration drawn from Chile?
