40 sepia-tone gelatin silver print photographs, approximately 6¼x8, housed in a period full leather album, "New Works" in gilt on front.

Images of the Anaconda Copper Works at Anaconda, Montana with exterior and interior views providing a tour of the plant in operation. Many of the photos showing workmen at their various tasks. The Anaconda Copper Mine was purchased in 1881 by Marcus Daly from Michael Hickey, a prospector and Union Civil War veteran. Daly then developed the Anaconda Mine in partnership with George Hearst, father of William Randolph Hearst, James B. Haggin and Lloyd Tevis of San Francisco. From this beginning grew the Anaconda Copper Mining Company, a global mining enterprise featuring the Anaconda and other Montana mines, a smelter at Anaconda, processing plants in Great Falls, Montana, and many other properties. Two additional photos laid in at rear, one a view of an unidentified office, the other a collage of portraits of unidentified gentlemen.
