In 1935, a newspaper of the League appeared, La Voix des femmes, a journal of expression for women, of which Yvonne was one of the main editors. In 1951, she founded L'Escale, a bimonthly magazine intended to be completely free, where she expressed herself or criticized writers, journalists and politicians in particular. She also strongly mobilized, through her League, for the expansion of women's right to vote, which resulted in the achievement of political equality between men and women in August 1957 and, therefore, women's right to vote.
