The "Bird's Nest" is one of the most difficult steel structure masterpieces in the world. Its construction was completely undertaken by the Chinese alone. Using their cerebal and manual powers, the Chinese workers created a building with the optimal visual effect: a metal edifice made to look like a bird's nest. This is indeed an immense architectural feat, unprecedented in sporting history. As a witness to the 2008 Olympic Games, the "Bird's Nest" is of large historic significance. As such, a metal model of the "Bird's Nest" is very much worth adding to any souvenir collection. The metal plates that accompany the models as labels are made from residual steel left over from the construction of the actual site.
The officially licensed products, ranging from medium to large sizes, were put on sale in licensed stores on September 19, 2007.

A model of the first truss structure of the National Stadium will hit the flagship store for Olympic licensed products on Wangfujing Street in downtown Beijing on December 23.
The steel licensed product is a 1:100 scale model of the truss structure of the stadium, also known as the "Bird's Nest," according to information from a launching ceremony on Monday for the fourth anniversary of groundbreaking for the main stadium of the Beijing 2008 Olympic Games.
The material of the model piece comes purely from residual steel from the stadium and was cast through precise founding technologies. Licensed by the Beijing Organizing Committee for the Games of the XXIX Olympiad (BOCOG), the article is issued with a limited circulation of 5,000 pieces.

Listed as one of the "ten best architectural marvels" by Time Magazine, the National Stadium was co-designed by Swiss company Herzog & de Meuron and China Architecture Design Institute. It looks like a cradle, or a bird's nest with interlocking branches and twigs, because of its grid formation.
The exterior of the National Stadium is formed by 24 portal truss frames, and the miniature licensed product is prototyped from the stadium's first truss structure, or its pile foundation, said Zhang Hengli, vice-general manager of the National Stadium Co. Ltd, who joined Tang Yonghong, a BOCOG official, in unveiling the product.
