This is a spectacular magical art for you to put together and is made with paper entirely. The building design is base on Notre Dame Cathedral. It uses a unique designed interlocking system that no glue is applied (except only two pieces are glued onto the baseboard and two pieces of baseboard are glued together.). All patterns of main body parts are printed on the high quality neutral pH and acid-free heavy paper, which can last for many years and will not turn brittle and yellow or fades with age. All parts are to be cut out. If you follow the instruction comes with the kit to cut each piece, you will find that the cutting is not difficult at all. The instruction included in this kit is an auto-run CD Rom. It contains easy-to follow diagrams and step-by-step instructions with a lot of detailed nice and clear photos. It works like a slide show either automatically or manually. It is auto-run for PC only. Macintosh user has to open each picture manually.
