This poster would have been made during the aftermath of the Tlatelolco student massacre, when the Mexican army attacked a gathering of unarmed student protesters. It is believed that the violence erupted when soldiers posing as civilian student attendees instigated police intervention. Military helicopters opened fire on the crowd while foot soldiers attacked with rifles and bayonets. In an effort to cover up the resulting carnage, the dead bodies were quickly gathered and disposed of. In some cases, the wounded were denied medical attention and died as a result. At the time, President Ordaz denied the whole event ever took place, hence the seemingly inocuous question 'What dead bodies?'. The government's conspiratorial denial and cover-up is unflinchingly addressed in the accusatory image of a corpse being fed into an incinerator. The collecting receptacles bear the mark of a government body; the DDF (Departmento del Distrito Federal) or Legislative Assembly of the Federal District.
