This illustrated book, published by Yang's Stamp Service in Kowloon, Hong Kong is an original 1st edition of the catalogue. 

The book is a valuable addition to any Chinese Philately collector's library and is written in English, making it accessible to stamp enthusiasts worldwide. 

 This catalogue covers a variety of non-fiction philately subjects, including a detailed account of the people's republic of China. 

The book is an original publication, not a facsimile, and is regionally manufactured in China. 

The book still has even still has the illustrations supplement showing clearer stamp pictures than in the original book printing.

This book is part of an old Chinese stamp collection I recently purchased.
