China National Philatelic Co. has loaded a lot into this set of five postcards commemorating 2025’s Year of the Snake.  These cards come in a cardboard cover and each has an (uncancelled) 1.20 stamp affixed, but these are not maximum cards.  Each has a legend (in Chinese) like “Money rolling in” or “Many happy events” in keeping with the benevolent wood snake, and the cards as well have QR codes so you can dig even deeper.  Quite complex, as postcards go.  Grade: 1
