Nearly two dozen laborers milling around a steam drill preparing to blast rock.
Scope and Content:
B. L. Singley founded The Keystone View Company in 1892 in Meadville, Pennsylvania. The company quickly became the world's largest view company, having at least 250,000 negatives (of which some 50,000 were available as numbered views) by the 1930s. These images were meant to bring international experiences into the palm of the average person's hand, to be revisted in private or during social gatherings. It has been said that the ability of the stereograph to bring vicarious experiences to faraway people makes this medium parallel to the internet or television today. The Keystone View Company also focused on the educational value of their products, employing teams of people to write explanatory texts that were printed on the backs of the stereograph cards. This text, along with the imagery, presents the dominant vision of American ideals and interests during the late nineteenth and early twentieth centuries. Source 1: Source 2:
