The Continent Stereoscopic Company was a major publisher of pirate and copy negatives (although they did issue some original work). They produced their views from their New York offices during the period 1870-1890. They claimed to have released over 2,000 views covering much of the American Continent. U.S. States given particular attention included Ohio, Pennsylvania, Washington, Oregon, Nevada and California. A great percentage of their views were of western scenes. Among the notable photographer of whom the company "borrowed" images were J. S. Mitchell, Enoch Conklin, C. R. Savage, Ben Wittick, F. Jay Haynes and William Henry Jackson.
Their Yellowstone issues are all of a single style. At this time only 3 are known.
The Giant Geyser Cone, Yellowstone Park.
