Unused set of five cards from 2001.  Here’s what you might want to know:  each card has pre-printed, coloured postage on the reverse, of an orchid but not necessarily the same orchid.  Each of those pre-printed stamps also shows one or another pollinating insect in one corner, and then in Korean and roman letters you can see the scientific names.  The main captions are in Korean only.  Grade: 1
