Albumen print. Stereoscopic card by E & H T Anthony of New York, of shoeshine boys posing against an advertising hoarding. Some of the attractions include the 'Weird Woman of the Glen', and General Tom Thumb (1838–1883), less than 3 feet high, who was appearing at Barnum's Museum. 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.
