Review title: Histomap of World History
Product review: For some time now, I've been searching for a copy of the "Histomap of World History: The Rise and Fall of Peoples and Nations for 4,000 Years" by John R. Sparks. I know that this must have been a controversial product, but it was also very useful as a starting point for discussions on the flow of time and the impact of different civilizations. This diagram has been out of print for some time, and now people who own copies of this chart are selling them on e-bay for progressively higher prices. Rand McNally should consider publishing an updated version based on the book "The World is Flat" by Thomas L. Friedman. It would be fantastic if they could offer a set of all three maps -- the original 1952 version, an update 1990 version, and the new "World is Flat" version.
