At the recent event at the Chinese Consulate to celebrate the 40th anniversary of the establishment of Ambassadorial Diplomatic Relations between the People's Republic of China and the United Kingdom (see this article), our Chairman Janice Dickson took the opportunity to mark a notable 40th anniversary for the SCA. She presented Consul-General Li with a copy of the first issue of Sine, which was published in Spring 1972.
There had been an earlier publication, called The Bulletin of the SCA, beginning in February 1968, but these were duplicated newsletters rather than a full magazine.
You can download a copy of this 1972 issue here. It includes articles on a wide range of topics, including Peking University since the Cultural Revolution, Chinese education, woodcuts, medicine, archaeology, and agricultural modernisation, as well as obituaries of Edgar Snow and Chen Yi.
