A shallow box binder cover is provided for a binder containing a plurality of pages. The cover has a stiff, opaque core through which a plurality of display openings are defined. These display openings are surrounded by the structure of the cover core. A separate transparent plastic blister or box is located in each of the display openings. Each transparent box has a raised interior bubble surrounded by a base having mounting flanges projecting laterally from opposite sides of the periphery of the base. These mounting flanges are held against the inside surface of the front cover core so that the raised interior bubbles project into the display openings and into close proximity to the outer surface of the cover core. A front cover liner is disposed across the bases of the boxes to define separate, hollow enclosed cavities within the interior portions of each of the bubbles. Selected three-dimensional objects are placed within the bubbles before the front cover liner is disposed across the bases of the boxes. These three-dimensional objects are thereby loosely entrapped within the bubble portions of the boxes in the display openings and are visible from the front of the binder cover.
