This striking Chinese definitive stamp from 1949 features a detailed design showcasing a steam locomotive and a modern ship, symbolizing progress in transportation. Originally issued as a 20¢ brown, it was later overprinted with a bold “50” surcharge in black to meet new postal rates during the early years of the People’s Republic of China. The traditional border design and clear overprint make this issue highly recognizable among collectors. Such surcharged provisionals hold strong historical significance, reflecting the transitional period in Chinese postal history. A fine addition for specialists in Asian philately and surcharge varieties.
