International expositions, held around the globe since 1851, have helped to shape the modern world. Unsurpassed in their scale and confidence, they rank among the most spectacular, popular and important events ever held. Following the enormous success of London's Great Exhibition of 1851, expositions have been held in Europe, America and Asia and provided a stage on which the world has come together to display its achievements and ambitions. This fascinating book traces the history and significance of expositions and is fully illustrated with posters, ephemera, photographs, books and catalogue plates.
