Known as the "Olympics" of stamp collectors, the World Stamp Exhibition is taking place in Wuhan in China's Hubei province from June 11-17. It exhibits several treasured and unique stamps, including some of the earliest stamp manuscripts in existence. China’s earliest stamp manuscript was designed by R. A. de Villard, a foreign maritime customs official during the Qing dynasty.  The “Coiling Dragon, Jumping Carp and Wild Swan” stamps were officially issued by the Chinese Imperial Post of the Qing Dynasty in 1897. Now they are in the hands of the China National Post and the Postage Stamp Museum. The manuscript provides valuable first-hand information for the study of postal history, stamps and postcards during the dynasty.
