1956 People's Republic of China Sun Yat-sen 90th Birth Anniversary Postage Stamps

This is a gathering of vintage postage stamps from the People's Republic of China, specifically focusing on the 1956 commemorative issue honoring the 90th birth anniversary of Dr. Sun Yat-sen. The upper stamps feature a detailed, fine-line engraved portrait of Sun Yat-sen in a sepia or chocolate brown monochrome ink on cream-colored paper. The text across the top, written in traditional Chinese characters, denotes the anniversary (1866-1956). Below these are green stamps commemorating the 8th National Congress of the Communist Party of China, also dated 1956. The stamps feature classic perforation edges, which appear slightly irregular in some areas, suggesting they may have been separated from a sheet manually. Physically, the paper shows some light toning and minor foxing consistent with their nearly 70-year age. There are visible postmarks on some specimens, indicating they were used in circulation, while others appear to be mint or lightly hinged. The printing quality is characteristic of mid-20th-century state-issued philatelic materials, utilizing high-contrast engraving to provide depth to the portraiture. The collection is currently mounted on a black acid-free backing paper within what appears to be a philatelic album, with a textured blue cloth visible in the background.
