The first half of the 20th century was a period of great change along the historic Ohio River corridor. It was then that the Ohio became the most heavily engineered river in the world, facilitating its use as an artery of commerce. It was also a period of great change in transportation as diferent means of travel appeared along the margins of this storied waterway. And it was the era of the picture postcard, in which postcard publishing companies chose views for the public to buy and share with family and friends via the United States Postal Service.

All of these themes are woven together through a fullcolor display of more than 150 historic postcards that takes the reader along a 981 mile journey from the industrial colossus of Pittsburgh, past its trailing southern elements, and into the mining and agricultural areas on the way to Cincinnati, once known as Porkopolis. From there, post- cards o er views of Louisville, once the tobacco capital of the United States, and through interesting but less famous places on the way to Cairo, Illinois, where the Ohio meets the “Father of Waters,” the Mississippi River, on more than equal terms.

Employing this unique collection of historic postcards as both artifacts and images, authors John Jakle and Dannel McCollum effectively illustrate the importance of the Ohio River in American history.
