People's Republic of China 1952 Yan'an Pagoda Postage Stamp

This is a used postage stamp from the People's Republic of China, issued in 1952 as part of the 'Revolutionary Holy Sites' series. The stamp is printed in a distinct carmine or rose-red monochrome ink on cream-colored paper. It features a landscape illustration of the Baota (Pagoda) Mountain in Yan'an, which served as the headquarters for the Chinese Communist Party during the late 1930s and 1940s. The denomination '10分' (10 fen) is clearly printed in the upper right corner. Below the central image, the text '中国人民邮政' (China People's Post) is displayed in stylized Chinese characters. The stamp exhibits a circular black postal cancellation mark (postmark) on the left side, which includes the character '京' (indicating Beijing) and a date stamp partially reading '11308'. The stamp has rough, perforated edges which appear slightly worn, a common trait for stamps of this era. The paper shows minor yellowing or oxidation consistent with its age, but the ink remains relatively vibrant. This piece represents an important historical period in Chinese philately, reflecting post-revolutionary iconography and early state-issued postal artifacts from the 1950s.
