The task of designing the complete way-finding sign­­age system for Expo67 in Montreal was entrusted by the Canadian Corporation for the 1967 World Exhibition to Paul Arthur & Associates Ltd. It was the first time that an entire graphic programme of official and commercial signage on such an immense scale – for the equivalent of a thousand-acre city – had ever been planned in advance as a modular system and integrated into a master planning concept. Pictograms of animals in black silhouette were used to identify the various areas of the two mammoth parking lots, each of which accommodated about 12,000 cars. – Burton Kramer
