"Tintin fans bought up all the limited-edition sculptures of Tintin with a suitcase with Shanghai and his dog Snowy printed on it," said Philippe Wang, a representative of China of Moulinsart, intellectual property owner of "The Adventures of Tintin."

"People are coming from Beijing and Hangzhou in groups this weekend just to visit our shop," said Wang.

To meet more customer demands, Wang said an official online Tintin shop will open soon, and a Tintin exhibition in China is in preparation.
