Advertising Device
Description:
Patent for an Advertising Device. This device provides "a series of hinged leaves so mounted that those exposed to view have the experience of being part of a book." (lines 14-17). "A further object is to provide means which will conceal the operating mechanism, and mystify the observer" (lines 23-25), with a "supporting structure and a dummy provided with a movable hand...for turning said movable shaft as the leaves are turned" (lines 3-13).
