Inside the New York Institute of Photography Prototype Camera

One of 17 contact prints featuring the prototype model of the 35 mm camera of the New York Institute of Photography, an Interior view, ca. 1925. Note by Carl Louis Gregory on verso: “Has regular gate—reflecting prism will be on door which will open at bottom like B&H [Bell & Howell]. Trick crank at rear like B&H. Round metal lens board on front for which an extra turret for 4 lenses may be substituted. How do you like it?”https://digitalcommons.chapman.edu/jonathan_silent_film/2585/thumbnail.jp
