This Photo album is the first volume of 3-volume edition of the history of Expo. Starting from 1851, the very first official Expo in London, and until the 2017 which will be held in Astana. Descriptions of each Expo, its importance, outcomes, interesting figures and what are the most important HD images. Moreover, there are archive images from the libraries and some comments of those who have experienced events themselves. This is one of the most live and amazing ways to find out what Expo is and how did it develop throughout almost 160 years.
