Established in 1820 on the banks of the Tennessee River, Decatur, Alabama, has always had its destiny tied to the water. It is the city's lifeblood and obstacle. A railroad, an "iron river" between Tuscumbia and Decatur, was built to overcome the natural obstacle so it could be used as an asset. This effort worked. War, pestilence, economic downturns, labor, and social unrest all imbued residents with a resilience of spirit. Residents knew it, and visitors sometimes described it in quick notes on cardstock. These postcards from Decatur, Alabama, traveled across the land and the world. Presented here for the first time are some of those cards, dating between 1874 and the latter 1970s.
