Similar in many ways to other Guangdong Philatelic boxed sets, this is a semi-hardcover item in a cardboard sleeve.  It measures 8-3/8″ x 11-1/4″ x 1/4″.  The book itself has three leaves, for a total of eight facings, and is fully bilingual in Chinese and English, providing in those few words almost all you might want to know about silk scrolls.  Contents include detached stamps, one 7-1/4″ stamp sheetlet, three stamped covers, and three stamped postcards (no postmarks) matching the covers.  Impressive, historical (Zhang Xuan), and Grade: 1.  Our entry 20307496B shows one sample card.
