He was the official photographer and concessionaire of Yellowstone National Park, the first national park in the USA, and is also widely understood to be the first national park in the world. Haynes grew up around his father, Frank Jay Haynes, who was the official photographer of Yellowstone National Park and who ran a successful photography business. Frank trained Jack in photography and business. Upon Frank’s retirement in 1916, Jack inherited the family business and continued as the official YNP photographer until his death in 1962. In 1921, when Frank died, Jack also inherited the physical studio outside of Yellowstone National Park and Frank’s archive of YNP photo negatives. In 1927, Haynes built photo shops (also known as picture shops) on the Mammoth and Fishing Bridge campgrounds as well as a larger facility on the Old Faithful Auto Camp.

These black and white photographs are in nicely preserved condition, age tanning consistent. Each measures 7.25"W x 9.5"L, combined weight U6.
