World's Fairs and Expositions have been part of our American Culture for more than 150 years. The fairs started out in a large exhibit hall, and as the years passed and the number of exhibits grew as did the number of buildings needed for the displays. Eventually many states, nations, and individuals would start building their own buildings. How many of these buildings are still standing? That was a major focus of the research of this book. Some fairs left several buildings while others have nothing to remind us of the glory of the fair. The book also focuses on the statistics and interesting facts about the fairs and expos.
