I am offering a set of four commemorative stamps from China, "90th Anniversary of the Birth of Comrade Mao Zedong." Catalog Number: J.97 (Complete Set of 4) Issue Date: December 26, 1983 Issuing Authority: Ministry of Posts and Telecommunications of the People's Republic of China These stamps were issued by the Ministry of Posts and Telecommunications of the People's Republic of China on December 26, 1983, to commemorate the 90th anniversary of Mao Zedong's birth. This set is the first in the Mao Zedong Birth Commemorative Series, and a rule was established to issue stamps on the same theme every 10 years thereafter. As sequels, stamps on the same theme were issued in 1993, 2003, 2013, and 2023, and the series name was unified from "Birth" to "Birthday." Stamp 1 (top left) is titled "1925 in Guangzhou." This stamp depicts Mao Zedong in Guangzhou in 1925. At the time, 32-year-old Mao Zedong held several important positions in the Kuomintang and published the first volume of "Selected Works of Mao Zedong," "Analysis of Classes in Chinese Society." The stamp depicts him as an intellectual wearing a blue coarse cloth changshan. Stamp 2 (top right) is titled "1945 in Yan'an." This stamp depicts Mao Zedong in front of a cave dwelling in Yan'an in 1945. In this year, the Anti-Japanese War was victorious, and the most difficult period of the struggle had passed. A slightly plump Mao Zedong is smiling, suggesting his confidence in victory. Stamp 3 (bottom left) is titled "1952 Inspecting the Yellow River." This stamp depicts Mao Zedong inspecting the Yellow River in Henan Province in 1952. The Yellow River is called the "cradle of the Chinese nation," but it has caused many floods over the years. Shortly after the founding of the People's Republic of China, Mao Zedong resolved to control the water and inspected the river conditions on site. The stamp depicts Mao Zedong looking out at the vast sky and river. Stamp 4 (bottom right) is titled "1961 in Jiangxi." This stamp depicts Mao Zedong in Jiangxi Province in 1961. It depicts Mao Zedong, who loved reading throughout his life, reading books enthusiastically. His light gray clothes and bright forehead contrast with the dark background, making the figure stand out more. This commemorative stamp set is a masterpiece issued as part of the Mao Zedong Birth Commemorative Stamp Series, and is perfect for collection and display. These are actually used, vintage stamps. They are in good condition for used, vintage items. Please check the images for details. No returns or exchanges. Shipping costs will be covered by the seller.
