William Henry Jackson took a black-and-white view in 1890 of the Louisville & Nashville's Biloxi Bay, Mississippi, trestle. He had been "down south among the cotton fields and sugar canes," according to Anthony's Photographic Bulletin. This bridge, one of the longest on L&N's gulf coast main line, was typical of several timber trestles between Mobile and New Orleans. "It was a very historic section of line," according to Charles Castner, a L&N historian. Jackson, with his negatives, moved from Denver to the Detroit Publishing Company in 1898. He converted the view to a "photostint" color postcard in the early 1900s. The Detroit company had exclusive North American rights to "photostiint," a new Swiss process that produced vibrant color prints from black-and-white negatives.
