The World's Columbian Exposition, celebrating the 400th anniversary of Christopher Columbus's 1492 landing on American shores, was actually held in 1893. Forty-six nations participated in the exposition, which cost more than $28 million and drew almost 26 million visitors (equivalent to about half the U.S. population) during its six-month run. Each of the 30 fascinating images in this book of postcards, from the collection of the Chicago History Museum, document the excitement and innovation of this historic exposition.
