Featured in this lot are two (2) original F. J. Haynes photographs of Yellowstone National Park, circa 1930s. These are all large format photographs of Yellowstone National Park and are all stamped with the Haynes hallmark. Frank Jay Haynes, known as F. Jay or the Professor to almost all who knew him, was a professional photographer, publisher, and entrepreneur from Minnesota who played a major role in documenting through photographs the settlement and early history of the great Northwest. He became both the official photographer of the Northern Pacific Railway and of Yellowstone National Park as well as operating early transportation concessions in the park. His photographs were widely published in articles, journals, and books, and turned into stereogrpahs and postcards in the late 19th and early 20th century. The photographs are numbered and titled, "35888 Fountain Paint Pot", "13040 Old Faithful Geyser". The photos are stamped on the bottom right reading, "Haynes Yellowstone Park". Both photos show good condition overall with little to no wear present and no signs of obvious damage present. The photos each measure 11"W x 14"L approximately.
