This 1971 April Coalition/April 6th Movement silkscreen used the image of Reconstitution (after the Kent State students were killed) from a year earlier at the University of California campus.  The poster linked recent anti-Vietnam War imagery with City Council candidates Loni Hancock and Rick Brown.  April 6 was election day.

The peace symbol combined with the clenched fist was itself a strong political coalition symbol, meaning that liberals and radicals were working together against the Vietnam War. 

The electoral alliance that was the April Coalition and later became Berkeley Citizens Action (BCA) was part of the anti-war movement.  It's political opponents trace their origins back to supporters of the Vietnam War.
