Featured in this lot are Nine (9) pre-1917 stereographs of Yellowstone National Park, some from Underwood & Underwood Publishers and also the Keystone View Company, both which were pioneers in the production and distribution of stereographic images. Most people experiencing Yellowstone National Park at the turn of the 20th century weren’t visiting in person. Back then, travel was expensive and exhausting, involving lengthy train rides and uncomfortable stagecoaches, but technology did get them closer to the park via stereographs. A stereoscopic view, or stereograph, consists of two nearly identical photographs that are printed together on a card. When you view the card through a stereoscope, your left and right eyes combine the images, giving an illusion of spatial depth. Although stereographs can portray big events, urban scenes, or individual portraits, they have always been especially popular for places of stunning natural beauty, and one of the nation’s most beauteous spots is Yellowstone. Famed frontier photographers William Henry Jackson, Joshua Crissman, Thomas Hines and F. Jay Haynes produced complex stereographs designed to reward the viewers in the comfort of their homes. These stereographs are in good condition, some foxing noted, some are colourized. Measuring 3.5"W x 7"L
