This stamp block from the 2nd Shanghai Dah Tung printing, issued on January 6, 1949, features the prominent portrait of Dr. Sun Yat-sen, the founding father of the Republic of China. Designed as a daily use postage issue during the tumultuous final year of the Chinese Civil War, the denomination of 100 Chinese dollars reflects the inflationary pressures of the period. Printed using gravure on ungummed paper, the stamps display a rich brown hue and sharp impressions. Each stamp measures 23 x 27 mm and shows a clean layout with line perforation 14. The printing was done by Dah Tung Book Co., a notable printer for late Republic-era issues. The absence of gum and the consistent coloration indicate its unused and post-office fresh condition. The block is catalogued as Michel CN-IM 954, Scott CN-IM 890, Yvert et Tellier CN-IM 719, Stanley Gibbons CN-IM 1156, and China Stamp Society CN-IM 1353. As a complete and well-preserved multiple of 12 with excellent margins and registration, it holds historical and philatelic significance from a pivotal year in Chinese history. Estimate "$130 – 180"
