1930s Patent Document [Matted for Framing] for an Apparatus for Obtaining Criminal Confessions and Photographically Recording Them by Helene A Shelby
This is a wacky one that reads: The primary object of my invention is the provision of an apparatus for the creation of illusionary effects calculated to impress the subject with their being of supernatural character and to so work upon his imagination as to enable an inquisitor with a recording system...The graphic shows a skeletal image that the criminal sees...Wonderfully wacky...
