San Francisco: PIGJO, 1987. 8.5x11 inch flyer, printed both sides, very good, graphic motif depicts two earths as testicles appended to an ejaculating phallus. Four paragraphs of text on verso, plus various slogans. The SF Jacks online repository of "wank for peace" flyers does not inlude this example, an, ahem, seminal piece in the development of the genre. We have two versions, one side red and one side blue on white paper or one side red and one side black on white paper: Hamlet, or Horatio.
"Psychic detoxification of the world is the PIGJO! goal, friendly man-to-man outreach the means. PIGJO! was created by the Healing Order of Kthar Sissies of San Francisco to encourage Cosmorgasm, the joyous pleasurizing of everyone on earth at once..." The current incarnation of PIGJO is SF Jacks, which still holds events to celebrate the birthday of Ludwig Zamenhof, inventor of Esperanto. Group masturbation parties were one of the sex-positive responses to the AIDS crisis.
