Berkeley: No publisher, no date [ca.1969].
4to. Handbill from an anonymous Berkeley activist group suggesting that people buy whistles to notify when "pigs" are in the area or a bust is going down, and to take photos of undercover police. "And we are getting tired of being hassled, but we don't have to go away. We can fight back. Not by offing pigs, maybe, but by getting the word that they're around out before they get a chance to bust us." Sizeable stain to top right section, corner chip and a few tears, good only, but scarce.
