Paul Krassner was an American author, satirist and political activist, founder of the freethought magazine The Realist (1958-2001) and a key figure in the counterculture of the 1960s.

He is famous for writing “The Parts That Were Left Out of the Kennedy Book” (1967), “My Acid Trip with Groucho” (1981) and for designing/and/or/distributing the FUCK COMMUNISM! (1963) and Disneyland Memorial Orgy (1967) poster.

He was severely criticized by Robin Morgan in 1970 in “Goodbye to All That“:

“Goodbye to lovely “pro-Women’s Liberationist” Paul Krassner, with all his astonished anger that women have lost their sense of humor”on this issue” and don’t laugh any more at little funnies that degrade and hurt them: farewell to the memory of his “Instant Pussy” aerosol-can poster[1], to his column for the woman-hating men’s magazine Cavalier, to his dream of a Rape-In against legislators’ wives, to his Scapegoats and Realist Nuns and cute anecdotes about the little daughter he sees as often as any properly divorced Scarsdale middle-aged father; goodbye forever to the notion that a man is my brother who, like Paul, buys a prostitute for the night as a birthday gift for a male friend, or who, like Paul, reels off the names in alphabetical order of people in the women’s movement he has fucked, reels off names in the best locker-room tradition—as proof that he’s no sexist oppressor.”– “Goodbye to All That” (1970) by Robin Morgan

The entire issue where he is depicted with a spray can of “instant pussy” referred to, can be read here[2].
