The book is a good until page 175. Here the author purports that Frank Millet invented the paint system that made the White City white, when it was Joseph Binks who invented it and provided it to the fair. Joe invented it prior to the fair when faced with painting the huge basements at the Marshall Field's store where he worked as an engineer.After all, the spray paint gun is called a Binks, and the fact that Joe's invention made the White City white in an incredibly short time is what made his company, Binks Spray Sytems, later Binks Manufacturing, an international success shortly after the fair. Who has ever heard of a Millet Spray Gun?Unfortunately, this type of error causes all the facts in the book to be questioned.
