A print medium that is expandable and collapsible comprises two sheets separated by at least one collapsible brace. The collapsible brace includes a first wall attached to one of the sheets and a second wall that swings in relation to the first wall. The swinging motion of the second wall in one direction expands a distance between the two sheets, while a swinging motion of the second wall in the opposite direction collapses the distance between the two sheets. At least one sheet of the paper may include an ink receiving layer. When the collapsible brace is expanded, the print medium becomes a substantially rigid structure. |
