From 2016, a set of four cards showing blue, grey, orange-blue, and light brown ice flowers.  Being official cards, they have pre-printed “Postage pre-paid” on the back, for worldwide use.  As a side note, we planned to call these “Collectible postcards” and then wondered if we were spelling that right … or should it be “collectable postcards”?  Off to Dr. Google, which came up with this:  “‘Collectable’ describes items able to be collected. (e.g., payments, keys). ‘Collectible’ describes items considered worthy of collecting by enthusiasts (e.g., coins, stamps).”  So, we suppose, both.     Grade: 1
