Abstract: A set of interlocking elements capable of being joined together to form a corner piece of a puzzle game that constitutes a three-dimensional pictorial representation of a structure. In one embodiment, the set of interlocking elements comprises a first element that can be folded into a corner configuration. A second generally planar element interlocks through a dovetail-type joint with the first element to maintain the first element in a folded, corner-like configuration. The first and the second elements are provided with image-bearing surfaces that constitute individual pictorial entities contributing to a complete representation of the structure. When the first and the second elements are interlocked, the image-bearing surfaces unite visually to provide image continuity over the exposed surface of the corner piece. In a second embodiment, the set of interlocking element includes three discrete planar elements that unite through male/female joints into a T-shaped configuration.

Abstract: In order to enhance the enjoyment of assembling a puzzle of the three-dimensional type, a puzzle is disclosed in the form of a building-like structure having walls to be joined at corners thereof. The puzzle includes a plurality of wall pieces capable of interlocking in a plane to form walls of the building-like structure. It is also contemplated that each of the wall pieces will have peripheral male and female contours capable of interlocking engagement to form a portion of a wall. The puzzle further includes at least one corner piece capable of joining a pair of walls at a corner of the building-like structure. It is also contemplated that the corner piece will be formed so as to have a groove in a backing material opposite an image-bearing outer surface of the same types which are also to be used for each of the wall pieces.
