Patent No. 2,533,526 was granted to Yvonne Bersia Snyder of Forest Hills, NY for a “Beauty Pillow”:
During sleep the tissues of the face are usually crushed or folded in the same position for hours at a time. For example, the flesh of the cheeks or face when flattened against the pillow during the sleeping hours pushes the skin forwards and settles in the hollows of the eyes where it produces wrinkles.
It is an object of this invention to prevent wrinkles or damaging of the skin tissues during rest.
Looks like it could also double as headgear for full-contact sports.
