I am selling a set of 5 used Chinese "Homeland Scenery" definitive stamps from the time period. Symbols:普22 & 普21 "Note: 'Great Wall' is 普21 (center, top row)" Issue Date: September 1, 1981 Issuing Authority: Ministry of Posts and Telecommunications of the People's Republic of China To introduce the natural scenery of various places in China, the Ministry of Posts and Telecommunications of the People's Republic of China issued these definitive stamps on September 1, 1981. This series aims to widely convey China's scenic spots as definitive stamps and to meet the demand for various denominations in postal services. It depicts five scenic spots across China, including historical sites such as the Great Wall, as well as diverse natural landscapes such as the Tian Shan Mountains, Huangguoshu Waterfall, the tropical scenery of Hainan, and the forests of Northeast China. The compositions, which make the most of the characteristics of each location, have individual appeal while maintaining overall harmony. The original Chinese names are as follows. Detailed explanations of each item are omitted. Stamp 1 (top left) design name: "Hainan Scenery" Stamp 2 (top center) design name: "Great Wall" Stamp 3 (top right) design name: "Northeast Forest Sea" Stamp 4 (bottom left) design name: "Tian Shan Mountains" Stamp 5 (bottom right) design name: "Huangguoshu Waterfall" There are two types of printing methods for this "Homeland Scenery" series of stamps: "普22" (complete set of 5) by photogravure and "普21" (complete set of 17) by engraved printing. The designs are the same for both. Therefore, the set of 5 stamps I am selling corresponds to 普21 because the design name of Stamp 2 (top center), "Great Wall," is engraved. All five of these stamps are used. There is some paper from the envelope attached to the back, but there is no damage. They are in generally good condition for used stamps from that time period. Please check the images for details. No returns or exchanges. Shipping costs will be covered by me.
