ABSTRACT:
A file folder comprises a rear panel of stiff paper-stock and a front panel of transparent plastic material connected to the rear panel along a hinge line. Preferably, the hinge line is provided by a soft crease in the front panel which defines an inturned margin adhesively secured to the rear panel. The file folder is durable, is relatively inexpensive to manufacture and decorate, and affords notations to be made thereon using a variety of writing implements. Several different embodiments of the invention are disclosed.
