Book excerpt: World's Fairs and International Exhibitions have always had a political as well as a commercial and cultural context. This was particularly true during the Cold War when America and the Soviet Union used architecture and design to represent their opposing political ideologies. Jack Masey served with the United States Information Agency from 1951 to 1979, for many years as Director of Design. This important new book draws on his recollections and extensive new illustrative material to detail the significant role played by architects and designers in shaping America's image during the cultural Cold War.
