One would think we have a standard way to describe items like this by now.  They each pose different obstacles.  Issued by China National Philatelic Corporation, this is a book in a 10″ x 10-3/8″ cardboard sleeve (pictured here).  Its informative captions are in Chinese and English, but not usually both languages on the same page.  It’s a book containing maximum cards (postmarked) and sheets of 15 mint stamps each on alternate pages, so there are eight facings with cards (one is shown as 20307508B) and eight of corresponding sheets.  After all that, there are several pages of first-day covers and miniature stamp sheetlets, followed finally by a “Philatelic Passport: Ancient Towns of China (I)” embedded in the inside back cover, though it can be removed.  We haven’t tried.

See what we mean?  If you want to know more, please ask.  It is a nice item, so busy with different things.  Grade: 1
