From The Denver Post:
In the early 1900s, William Pennington and Lisle Updike spent most days traveling the four corners area of Colorado, Utah, New Mexico and Arizona in a wagon photographing the people and landscapes. The pair of photographers were based in Durango, Colorado where they leased a small space on Main Street and operated a photography studio. They traveled to the mountains and photographed miners and townspeople and visited Native American Reservations and Pueblos making portraits of the people. Their partnership was short-lived and Pennington soon bought out Updike and took sole control of the studio.
These prints were recently uncovered by Denver Post librarians, tucked away in a folder in a file cabinet. The captions were hand written on the back of each print. Along with the prints, a page of the Denver Post newspaper showed that the prints were featured in the January 30, 1974 newspaper.
