Why does the opening of Milan's metro in 1964 matter for design?
Milan's Metro Line 1 opened on 1 November 1964 and brought Italy's design culture together in one place: Franco Albini, Franca Helg and Bob Noorda won the 1964 Compasso d'Oro for its architecture and signage, a "pioneering example of a unified system"; Pirelli supplied the rubber flooring; and Bruno Munari's Campari poster was the first hung on the platforms.
Munari's poster, "Declinazione grafica del nome Campari", breaks the brand name into fragments on red so it can be read from a moving train.
