Beautiful Shangri-La in Yunnan (Set of 10)

The paper cover for this set has a cut-out front window, and you can see one of the cards through that. They are somewhat generic, lacking captions, but readily identifiable to anyone who has travelled around Shangri-La. The set was issued by China Post in 2009, is unused, and each card has pre-printed 80 fen coloured postage. Grade: 1
