This research aims to develop cultural products for professional sales after producing creative products utilizing dinosaur characters, which are the representative exhibited item of dinosaur-centered museum. There are seven museums in Korea whose theme is dinosaur. There are three dinosaur museums among them, Goseong Dinosaur Museum at Kyungnam, Mokpo Natural History Museum, and Seodaemun Museum of Natural History. While inspecting cultural products within the museum shops of these three museums, general products occupy more than 80% of all the products rather than products related to dinosaurs, and has a problem that most products are decorative ones. This resulted from that enterprises supplying these products are not professional ones and are irrelevent to cultural industry; as result, purpose of conveying culture through products is lost. This research develops dinosaur characters utilizing computer 3D techniques in order to imbue unique characteristics to dinosaur museums and informing cultural speciality of our country. In addition, this research presented design method of cultural products by grafting traditional symbols onto these characters, and actually produced 11 items of 5 kinds: toys(dolls), clothes(T-shirts, pajamas, socks), stationery(notebooks, memo), accessaries (bags, umbrellas, handkerchief), and others(cups). On the items above, dinosaur characters are variously utilized in form of printing, embroidery, and stickers by using computer 3D technique. A cultural product is a tangible form which could show variety of cultural characteristics of our nation that could spread the culture through the consumers, and such type of purchasing could increase values of cultural industry by creating economic profits; such points are the significance of this study.
