A binder for papers, photographs, or other sheet-like materials is provided
with a cover having one or more window openings defined therein. A flat,
transparent protective sheet is located in contact with the inside surface
of the binder cover and a backing sheet overlies the protective sheet. The
backing sheet is secured to the peripheral margin of the protective sheet,
and elsewhere as required, to delineate at least one, and preferably a
plurality of pockets. The pockets are formed between the backing sheet and
the protective sheet. An elongated slit in defined through the backing
sheet behind each pocket created. The peripheral edges of the backing
sheet are permanently secured to the inside surface of the binder cover.
Photographs or other flat display materials may be inserted into the
pockets formed between the backing sheet and the protective sheet through
the elongated slits. The pockets are delineated so that they are aligned
with the window opening in the cover. The photographs or other display
materials may thereby be viewed through the window openings from the
outside through the transparent protective sheet. Selected display
materials may be inserted and withdrawn from the pockets through the
elongated slits in the backing cover.
