Striking regional-issue stamp from the East China Liberation Area (華東人民郵政), originally printed in blue with an industrial scene showing a steam locomotive and worker in mountainous terrain. This example bears a bold red overprint featuring large characters “拾圓” (10 Yuan) along with additional regional control markings and stars, typical of transitional Communist postal issues in 1949. These local surcharges were applied during the currency reforms as postal rates shifted rapidly. A highly desirable item for specialists in Liberated Areas, overprints, and early PRC postal history.
