Commemorate the opening ceremony of the 29th Olympic Games. The first day cover is postmarked by China Post Company on August 8th, and it is out of print.

Well, I didn't see it clearly, and the diving team's autograph. This is hard to estimate. As far as I know, it seems that someone offers 6000-9000 for sale, but some first day covers can reach 1 million. It is estimated that your first day cover should not exceed 5w, and I can't give you the exact number! !
