The whole thing comes in a cardboard cover measuring 8-1/2″ x  10″ (shown here).  Inside, one piece that folds open to four panels.  Do that, and on one side, each panel holds one postcard of a different sport (Cross Country Skiing, Alpine Skiing, Biathlon, and Freestyle Skiing.  The cards of course are unused though each has an uncancelled stamp corresponding to the card’s particular sport.  Now, flip this whole thing over and one of the panels has bilingual Chinese/English text, and one has a mint set of eight of those stamps.  Another panel has details of issue from China National Philatelic, with QR code and holographic sticker guaranteeing authenticity.    See our entry 20307930B for one panel.  Grade: 1
