The Hong Kong Study Circle was founded in 1951 to record and circulate information on the postage stamps and postal history of Hong Kong and the Treaty ports.
Whilst it is UK-based, regular meetings are also held in Hong Kong and Canada.
The study circle publishes a Bulletin which is the medium for reporting, exchanging and recording information, normally submitted by members. The Bulletin has been published continuously since 1951 and is issued quarterly free to members.
