The foldable shelf system comprises one or more unfolded sheets that may be folded to form a shelf system. The shelf system may be mounted on a wall and may be operable to display a publication and a token. The publication may be displayed while held in a vertical orientation. The token may be displayed while resting on a shelf. As non-limiting examples, the publication may be a comic book, a magazine such as a sports magazine, a journal, or a photograph. The token may be an action figure, autographed memorabilia such as an autographed baseball, or an award such as a trophy or a ribbon. The display of the publication and the token together on the shelf system may suggest an association between the publication and the token.
