This newly processed collection consists of 21 albumen process stereograph cards of various Kentucky landscape scenes taken by local Lexington photographers Carpenter and Mullen. James A. Mullen, founder of Carpenter and Mullen, had an illustrious career in the 1860s. He operated galleries in New York and Cincinnati, worked for a Cincinnati photographer, the Engineering Corps, the State Geological Survey, and the Engineers of the Cincinnati Southern Railroad before settling into his Lexington Main street gallery.
Stereograph cards are an early form of three-dimensional photograph. First introduced in the 1850s, they were most popular between 1870 and 1920. To create stereograph cards a camera with multiple lenses, such as the one on the right, was used.
