N.p.: N.p., 1947. Unique photo album. Screw-bound folio. One hundred tipped-in black and white silver gelatin prints by noted naturalist Lewis Walker. Published ephemera relating to some of the images laid in. One article in the November 1945 issue of "Natural History" is SIGNED by Walker and inscribed to friends. Photograph sizes vary; some are as large as 12 1/2 x 9 1/2 inches, some are 7 x 5 inch prints, but many are 8 x 10 inch prints; a few in unusual sizes. Mostly ornithological in nature, but also some photographs of insects, the Hawaiian mongoose, and waterfalls, many photographed nocturnally. Walker was a pioneer of nocturnal images of birds. The quality of the photographs, both day time and nocturnal, are uniformly exceptional and the album is artfully arranged. Walker published a book on owls in 1974 and was widely published in National Geographic and other nature journals. Some wear from handling, glue spots from pasting evident on some images, overall very good in screw-bound canvas covered boards.
