The left border reads: "This Drawing is a reproduction of the Original on a reduced scale." Includes the printed British "Patent Specification" document, seven pages on four sheets, which describes the objective of the improvement as simplifying "the construction of the camera as well as the feeding of the film past the exposure aperture and the insertion and withdrawal of the film spool." The specification sheet bears a "U.S. Patent Office Library" ink stamp on the first page. In fine condition.
