Graphic artist Fré Cohen (1903-1943) grew up in a socialist working-class family in Antwerp and Amsterdam. Fré's talent for drawing becomes apparent at an early age and she wants nothing more than to develop her talent. However, this is not self-evident in those days: women fight for the right to vote, are expected to marry and stop working, and in the years after World War I Europe is still quite disorganized. In the 1920s, an optimistic wind nevertheless blows in Amsterdam, and the Socialist International and the peace movement bring together young people from all over Europe. In these circles, Fré's talent does not go unnoticed and she begins to create posters, book covers and brochures. When the economic crisis hits in the 1930s and fascism rises, Fré is increasingly confronted with her Jewish background, until she can no longer do her work openly and has to go into hiding. In The Letterbox, Edith Brouwer reconstructs the life of Fré Cohen. She not only paints a beautiful portrait of an inspired artist but also a picture of the 1920s in Amsterdam, followed by the threat and destructive power of fascism.
