The international typographic style, also known as Swiss style, is a trend in graphic design developed in Switzerland in the 1950s by Armin Hofmann and Emil Ruder. It emphasizes simplicity, readability and objectivity, using sans-serif fonts as the main and structuring element of the design. Among the corporate identities and logos emblematic of the international style are American Airlines (1967, Massimo Vignelli) Fiat, (Jean Reiwald and Armin Vogt), or Swissair (1978, Karl Gerstner).
