16.5 x 12.5” brown string-bound album with a frame pattern and “Photographs” on the front cover along with a sticker reading: “Holyoke Water Power Co.’s New Hydro-Electric Plant 1949-1952.” This album contains nearly 100 black and white photos documenting the impressive process of constructing the plant. The first photo is a copy of a photo from 1885 and features a view of the old timber dam undergoing repairs, with a note on the verso that says “still stands some 180 ft. behind the present dam.” Most of the photos are large and provide a sharp, detailed view of the many steps in the construction process. One figure who is shown frequently is Ed Jacot, who appears to have been a member of the Safety Engineers Officers and likely drafted or oversaw the development of the plant. Photos measure between 3.5 x 3.5” and 14 x 11” and are held to the pages with corner tabs. A few photos have comments written on the back, but not all. Most of the pages have come loose from the binding. At least one photo appears to be missing.
