1949 PRC Commemorating the First Plenary Session of the CPPCC Stamp (Northeast China Overprint)

This is a significant philatelic item from the early People's Republic of China, specifically the 'Commemorating the First Plenary Session of the Chinese People's Political Consultative Conference' issue. The stamp is printed in a deep red monochrome on off-white paper with visible perforations. It features a central emblem depicting a globe and a red flag within a cogwheel, set above a stylized illustration of the Xinhua Gate (the entrance to Zhongnanhai). A distinctive feature of this specific specimen is the vertical overprint text '東北' (Northeast) and '貼用' (For use in), indicating it was designated for use in the Northeast China postal region. This was common during the early transition period when different currencies circulated in various liberated areas. The bottom margin contains set numbers '纪 2. 4 - 1' and plate number '(13)'. The stamp appears to be in unused condition (MNH or MLH depending on the reverse), showing crisp edges and distinct perforations, though the paper shows slight natural aging and toning consistent with its 1949/1950 production date. The print quality reflects the lithographic or typographic standards of the period, demonstrating bold political iconography used to celebrate the founding of the new state.
