Hello, this item is a framed photographic diptych featuring a chambered nautilus shell, credited to William A. Conklin and dated 1978. The composition combines a standard photographic print and an X-ray-style image, highlighting both the exterior and interior spiral structure of the nautilus—an iconic motif linked to mathematical proportions and natural design. William Conklin, better known as an architect and archaeological preservation specialist, also produced photographic and scientific art pieces during the late 20th century, some of which circulated in museum gift shops and educational institutions.

While not classified as fine art photography in the traditional sense, pieces like this hold collectible interest for their vintage scientific aesthetic and association with Conklin’s broader body of work.
