In just half a century of growth, the art fair industry has transformed the art market. Now, for the first time, art market journalist Melanie Gerlis tells the story of art fairs' rapid ascent and reflects on their uncertain future. From the first post-war European art fairs built on the imperial 19th-century model of the International Exhibitions, to the global art fairs of the 21st century and their new online manifestations, it's a tale of many twists and turns. The book brings to life the people, places, and philosophies that enabled art fairs to take root, examines the pivotal market periods when they flourished, and maps where they might go in a much-changed world.
