Albumen print. Stereoscopic card by E & H T Anthony of New York. A busy street scene with pedestrians carrying umbrellas, and traffic consisting of horses and carts. A card such as this would be viewed through a stereoscope, and when one eye viewed each image, the picture would appear to be three-dimensional. Stereoscopes became popular scientific toys, and were a feature in many households in the late 19th century.
