Ornithology (Bird) Photo Album Vol. I of IV (Early 1900's). Beautiful antique study of bird photography. Cannot determine the photographer. There are approximately 498 - mostly 4.5" x 3.5" photos. Based on Google Image comparing a few of the images, the photos are from the U.S. east coast. The photos are adhered to the pages , so they cannot be removed without damage. Not all pages have 4 photos, some are empty.
