The postal history of Hong Kong and the Treaty Ports has been extensively studied and researched over the years but the period of 1917 -1930 during which the Hong Kong issues were overprinted 'China' has been largely overlooked
You can learn more about the history of the overprints here
The aim of this site is to:
If you want to help this site grow, I am always looking for updated images, new research, any postal history (covers, envelopes, postcards, anything with the 'China'; overprinted stamps on it!) stamp registration letter singles or blocks, images of missing or new varieties, earliest and latest recorded dates (ERDs and LRDs), or anything you think would be of interest.
If you contribute something that is added to the census of covers, I will donate to the philatelic organization of your choice! Please do not hesitate to reach out.
Or email us directly at Mail@ChinaOverprints.com
(Please ensure that any scans are at least 300dpi and preferably 600dpi, and if you can identify the subtype of cancellation, that would be appreciated)
