If you are strictly into botanical postcards, this is a nice one for you, issued by the PRC Government in 1999 as part of a set, then mailed in (we think) 2013.  It has postmarked pre-printed postage, and one extra uncancelled stamp.  Otherwise known as primrose, this particular variant — yes, even in the scientific world — seems to be in doubt about its genetic background.  The postcard, however, is rock solid.  Grade: 1
