A folded structure of paper, plastics, malleable metal or other foldable laminar material is formed of two or more members and is held together entirely by the interengagement of tabs and slots on the members. The positioning of the tabs and slots is such that, as well as holding the members of the structure together they define the shape of the structure having a recessed central region surrounded by a border portion having an overhanging lip serving to assist in holding in place pictures, postcards or like display material. Separators in the recessed central region can also be provided to hold postcards or the like which are smaller than the area of the central region.
