The one I'm looking for is a schoolbook I had as a small child: Mon Petit Livre Rouge – I assume that this was a reader used universally throughout the Francophone world, and Mao Tse Tung, in some incarnation as a boy in a mission school, came across it. A very cute book with line drawing illustrations of children. A red cover (obv). Have never come across a copy as an adult. Michel Audiard seems to have used the name for a book too. Not the one I'm after, neither his nor Mao's!
