Issued on December 1, 1942, to commemorate the first anniversary of the so-called "Greater East Asian War," this rare pair of mint never hinged blocks from Manchukuo presents both denominations of the issue: 3 fen and 6 fen. Each denomination features a detailed depiction of official government buildings symbolizing Japanese-occupied authority in Manchuria during the Second World War. Printed in purple brown using lithographic techniques, the stamps exhibit a clean and formal aesthetic consistent with wartime propaganda. The issue was perforated 13 x 13½ and bears the distinctive commemorative overprint, emphasizing imperial ambitions in the region. The edition was notably limited, with only 2.6 million of the 3 fen and 2 million of the 6 fen printed. These are cataloged under Michel CN-MA 137–138, Scott CN-MA 148–149, Yvert et Tellier CN-MA 135–136, Stanley Gibbons CN-MA 143–144, China Stamp Society CN-MA MC140–141, and Sakura CN-MA 143–144. This offering consists of two well-matched blocks of nine, both in excellent condition with fresh gum and uniform centering, representing a significant collectible from the geopolitical complexity of 1940s East Asia. Estimate "$150 – 200"
