China 1945, mint never hinged block of four featuring the 1 Chinese dollar Martyr of the Revolution issue with black Mengkiang overprint, released during Japanese occupation in July 1945. Printed in brown-orange by gravure, the stamp honors revolutionary figures and was repurposed for use in the Meng Chiang puppet regime through localized overprints. Measuring 22 x 24 mm and unwatermarked, this occupation issue reflects wartime adaptations of nationalist imagery for regional control. Cataloged as Scott 2N127, Michel JP-MG 118, Stanley Gibbons JP-MG 138, and China Stamp Society CN-IM MK258. The block is post office fresh with full original gum, strong impressions, and uniform overprints. Estimate "$110 – 135"
