I am offering a commemorative stamp from China, "60th Anniversary of the Founding of the Geological Society of China." Catalog Number: J.79 Issue Date: August 25, 1982 Issuing Authority: Ministry of Posts and Telecommunications of the People's Republic of China The Geological Society of China was established in Beijing on January 27, 1922, with 24 prominent geologists, including Zhang Hongzhao, Ding Wenjiang, Weng Wenhao, and Li Siguang, as initiators. It is a formal member of the International Union of Geological Sciences (IUGS) under UNESCO. Initially, the society had 77 members, 28 of whom were foreign members. By 1982, the society and its branches had over 40,000 members. Since the founding of the People's Republic of China, the society has been committed to uniting geological scientists and technicians, disseminating geological science knowledge, publishing research results, cultivating talent, and promoting academic exchanges both domestically and internationally. As a professional society with international influence, the Geological Society of China has contributed to the development of geological science in China and the world. On August 25, 1982, the former Ministry of Posts and Telecommunications of the People's Republic of China issued this commemorative stamp to celebrate the 60th anniversary of the founding of the Geological Society of China. The main design of this stamp is the emblem of the Geological Society of China, with a geological hammer, a tool used by geologists in field surveys, depicted below it. The background is black, giving an overall impression of solemnity and seriousness. In the center of the design is the emblem of the Geological Society of China, composed of five seal script characters: "土・石・山・水・中" (earth, stone, mountain, water, middle). A geological hammer and a geological compass are placed at the bottom, with the open compass representing the denomination "8." The gold-printed "8" resembles a treasure gourd, symbolizing the mission of mineral resource exploration. The dark background and light spots represent the vastness of the universe and abundant minerals. This stamp, as a commemorative stamp on the theme of geology and science and technology, has both documentary and collectible value. It is in good condition for an item that was actually used at the time. Please check the images for details. No returns or exchanges. Shipping costs will be borne by the seller.
