This negative size was 116 roll film, very commonly used in Kodak Brownies for many decades. The large negative meant photo processors could run off snapshot-sized prints via contact-printing, eliminating the need for an enlarger in the operation. The ones in our family collection date from 1919 to my earliest baby photos in 1947. Later, around 1956, my brother experimented with the film using an old Kodak folding camera, and I did the same around 1962.
