An article comprising a single flat sheet of material defining a central portion and at least two versatile portions foldably connected together, whereby: the central portion comprises a first edge , and two opposed second and third edges , shorter than the first edge, the central portion further comprising spaced first and second engagement means located adjacent the two opposed edges, whereby the two opposed edges are configured to be brought together to form a three-dimensional form, the first edge further comprising a first edge portion and a second edge portion, such that the first edge portion is at one end of the first edge, and the second edge portion is at the extreme other end of the first edge, such that when the first edge portion and the second edge portion are brought together, the central portion is erected into the three dimensional form and is secured by the engagement of the spaced first and second engagement means, and is foldably connected to the versatile portion, and whereby at least one of the at least two versatile portions is disposed at a location along the first edge between the two opposed edges so that it can form a background, foreground, internal portion, a side, a top and a base to define an application adopted by the at least one of the at least two versatile portions, and whereby the at least two versatile portions are adapted to be foldably connected to the central portion via a fold, and are adapted to be folded to a position adjacent to or at an angle to the front side or rear side of the erected three dimensional form, whereby the first edge defines a bottom end when the central portion is erected into the three-dimensional form, with the first edge terminating at the second and third edges of the central portion, and whereby a lower end of the erected three dimensional form has a curved periphery, or a periphery that consists of a plurality of straight lines, so that the central portion has a generally inverted cone shape that tapers in an upward direction. the central portion comprises a first edge , and two opposed second and third edges , shorter than the first edge, the central portion further comprising spaced first and second engagement means located adjacent the two opposed edges, whereby the two opposed edges are configured to be brought together to form a three-dimensional form, the first edge further comprising a first edge portion and a second edge portion, such that the first edge portion is at one end of the first edge, and the second edge portion is at the extreme other end of the first edge, such that when the first edge portion and the second edge portion are brought together, the central portion is erected into the three dimensional form and is secured by the engagement of the spaced first and second engagement means, and is foldably connected to the versatile portion, and whereby at least one of the at least two versatile portions is disposed at a location along the first edge between the two opposed edges so that it can form a background, foreground, internal portion, a side, a top and a base to define an application adopted by the at least one of the at least two versatile portions, and whereby the at least two versatile portions are adapted to be foldably connected to the central portion via a fold, and are adapted to be folded to a position adjacent to or at an angle to the front side or rear side of the erected three dimensional form, whereby the first edge defines a bottom end when the central portion is erected into the three-dimensional form, with the first edge terminating at the second and third edges of the central portion, and whereby a lower end of the erected three dimensional form has a curved periphery, or a periphery that consists of a plurality of straight lines, so that the central portion has a generally inverted cone shape that tapers in an upward direction. <EOS>
