We’ve opened the cover to show you the set of four stamps, released in November 2022, that’s attached in a sleeve to the inside front cover.  Issued by China National Philatelic, each of the 12 cards (we show the front of one) represents an animal in the Chinese zodiac, and eh has an individual historical caption (in Chinese) on the reverse.  QR and barcodes on the back of the cover might tell you more, but this set should have great appeal for anyone specialising in Oriental astrology.  Grade: 1
