Untitled (Pass Bridge) c. 1860s

"Untitled (Pass Bridge)" is a stereoscopic photograph, meaning that it comprises two nearly identical images that create a three-dimensional effect when viewed through a stereoscope. The photograph depicts a stone bridge over a small stream, surrounded by trees and foliage, likely taken in the 1860s by an anonymous photographer. The image is housed in the Art Institute of Chicago and provides a glimpse into the landscape of the 19th century. Stereoscopic photographs were a popular form of entertainment during this era, offering viewers a unique and immersive visual experience.
