Issued on March 1, 1941, during Japanese occupation, this mint never hinged lower margin block of 50 is part of a special issue for Manchukuo's postal savings program. These non-postal fiscal stamps were intended solely for savings account use at post offices, especially in rural areas where banking infrastructure was limited. The stamp depicts a vibrant red design featuring two carp circling a pearl in a decorative bowl, a motif symbolizing prosperity and good fortune. The Chinese inscription at the top reads "One chiao (10 fen)," while the bottom text identifies it as a "Postal Savings Stamp." Printed by photogravure on unwatermarked paper with a whitish rubberized reverse, the stamps were issued in sheets of 100 with comb perforation. The selvedge at the bottom bears the full 12-character inscription translating to "Made by the Japanese Imperial Printing Bureau." Catalogued as Scott MA 111, this vivid and culturally rich issue represents wartime Manchurian fiscal policy and East Asian symbolism. The block is in pristine post office condition with full gum and bright, uniform impressions throughout. Estimate "$220 – 280"
