A set of two unused cards from 2007, in China Post’s original packaging.  Both cards have pre-printed postage on the reverse, and serial numbers denoting that they were to be entries in a lottery.  In addition, the red card in the set has a large round (and red) printed seal in the message area, saying “Best wishes from the on-site opening ceremony” in Chinese and English.  Very nice addition to your collection of Olympics postcards.  Grade: 1
