Our scan shows the cover and one of the 16 unused cards in this set.  They have heavily serrated edges, and generally show ethereal local scenes, with captions on the fronts (in Chinese) of which this is typical:  “The breeze caresses the lake.  Wrinkled waves, Create ripples and cleanse the soul”.  We somehow missed the romantic side of Shuanglang, but these postcards will lead you right to it.  Grade: 1
