Origin of The Pocket Protector (Dec, 1950)
Plastic Liner Protects Shirt Pocket From Damage by Pencils
If you carry sev-eral sharpened pencils in a shirt pocket, this easily made plastic liner can be used to protect the shirt from being soiled or damaged by the pencils. Just cut a strip of sheet plastic to fit snugly in the pocket, heat the plastic and bend it double, leaving a space the thickness of a pencil between the plastic folds. Then bend down one end of the plastic to slip over the edge of the pocket.
