This is a softcover book, measuring 8″ x 8-3/8″, with a removable yellow sleeve (cover, and sleeve, pictured separately).  The title of this book, Flags, is accurate but misleading because the flag on each card is always the same–China’s national flag–and appears on the end stub of the card.  Here is how the book is organised:

Open to the inside front cover, and facing page, of much Chinese text and what is (to us) a mysterious diagram that looks a lot like a musical score, but with numbers and words instead of notes.  The next leaf is a type of semi-transparent onion-skin page divider with Chinese text and some graphics.  The next leaf consists of two se-tenant postal cards with pre-printed postage (not maximum cards):  one is a scene of Yida Huizhi and the other of Jinggangshan.  The book has 19 leaves altogether, including the dividers; the cards range from sepia to full color.  Cards have Pinyin titles but no English, and altogether there are 18 cards, two to a page.  Unused, of course.    Grade: 1
