A careful look at antique maps reveals plenty about how America has changed as it has expanded. We’ll talk this hour about what we can learn from maps with University of Texas at Arlington special collections curator Ben Huseman; Texas Map Society president Gerald Saxon; and Imre Dembardt, Professor of Cartographic History at UTA. They’ll take part in this week’s Virginia Garrett Lectures on the History of Cartography and the accompanying Map Fair of the West.
