The Little Red Book was actually compiled by members of the Gang of Four as part of their campaign to nearly deify Mao Zedong in order to ride on the crest of the wave that they were raising him on. It certainly was a prominent tool during the Cultural Revolution of the mid-1960s and was even brandished by rioting students in Paris during the incidents of 1967. Consisting of excerpts from various essays written by Mao in the 1950s but also a few bits from the days of the Long March, one that stands out for me is "Power flows from the barrel of a gun."

Then, of course, there's always John Lennon's "Happiness is a Warm Gun". I could make a joke about (Groucho) Marxist-Lennonist thought here but just won't.
