2. The information carrying device according to claim 1, wherein surfaces of the device body portions of the puzzle are labeled or printed with advertising information thereon.
3. The information carrying device according to claim 1, wherein the USB storage unit contains multimedia information for advertising.
4. The information carrying device according to claim 1, wherein the device body of the puzzle includes a plurality of cutting lines that separate the portions of the device body and that, together with the folding lines, enable the puzzle to be turned into different shapes.
5. The information carrying device according to claim 2, wherein the USB storage unit contains multimedia information for advertising.
6. The information carrying device according to claim 1, wherein the device body of the puzzle is rectangular box shaped when it is in the first shape.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
