People's Republic of China 1952 1600 Yuan Charcoal Gray Miners Postage Stamp

This identifies as a 1952 postage stamp from the People's Republic of China, part of the 'Workers' or 'Productive Occupations' definitive series. The stamp depicts two coal miners in a dynamic, social-realist style, featuring specific details such as safety helmets with lamps and mining equipment. It is printed in a monochrome charcoal gray or deep olive-green ink on off-white/cream-colored paper. The denomination '1600' is prominently displayed in the lower right corner, followed by the Chinese character for 'Yuan'. The text at the bottom left reads 'Zhongguo Renmin Youzheng' (China People's Post). The stamp shows physical characteristics typical of the era, including rougher perforations. Condition-wise, the stamp appears to be in 'used' or 'hinged' vintage condition with moderate centering. There are visible signs of aging, specifically yellowing or toning of the paper stock and some softening of the perforation tips on the right edge. No visible postal cancellation mark is prominent in this view, though some light smudging may be present. The engraving quality reflects the industrial aesthetic of the early PRC period.
