Holding apparatus with foldable trifold structure

An apparatus for retaining printed material comprising:

• a foldable body having a first portion and a second portion, wherein:
• the first portion is configured to be folded relative to the second portion to define a first fold extending along a lateral axis of the foldable body;
• the first portion having a least:
• a rectangular region having an area defined by four points within the first portion, wherein:
• a first boundary of the rectangular region extends from a first point to a second point,
• a second boundary extends from the second point to a third point,
• a third boundary extends from third point to a fourth point,
• a fourth boundary extends from fourth point to the first point, and
• wherein the second boundary, third boundary, and the fourth boundary are each configured to define incisions in the first portion such that the first boundary is permitted to be folded relative to a remaining area of the first portion to define a second fold extending along the lateral axis;
• the second portion having a least a base region and a protruding region, wherein the protruding region is folded relative to the base region to define a third fold extending along the lateral axis;
• and
• wherein, when the first boundary is folded relative to the remaining area of the first portion, the third fold is configured to receive an end defined by the first boundary and thereby provide a recess in the first portion corresponding to the area of the rectangular region.
