The Ghost in the Stereoscope
Founded in 1854, the London Stereoscopic and Photographic Company was a major publisher of stereographs-cards with two nearly identical photographs mounted side by side that can be viewed through a binocular device to create an illusion of depth. The firm's output was colossal; their 1858 catalogue listed more than one hundred thousand views. While the majority of these were landscapes or architectural views, there was also a thriving market for staged historical, sentimental, or comic tableaux, which were often hand-colored to enhance their dramatic impact. Among the most popular themes were courtship, marriage, unrequited love, bereavement, children sleeping or praying, fairy tales, fortune telling, and supernatural scenes involving ghosts or spirits.
