One of the most innovative French graphic designers, Catherine Zask's posters have the elegance and coherence of DNA, and indeed she works with the building blocks of writing and communication--letters. Here, in Poster Collection 12, the series from the Zurich Museum fr Gestaltung, she allows the letters free rein to be musical, to trigger echoes, to store images, but never unmoors them from their task of providing written communication in an appropriate and comprehensible form. The dialogue with the client and the public is crucially important to Zask: "I make graphics to include the others." Her work for SCAM (Societe Civile des Auteurs Multim dia), the Hippodrome theater in Douai, and the cole d'Architecture Paris-Malaquais are evidence of the remarkable clarity and unmistakable individuality of her work.
