This mint never hinged full sheet of 100 stamps from the 1921 "Workers" definitive series of the German Reich features the 80 pfennig denomination in a deep blackish rose hue. Designed by Paul Neu, the illustration depicts two blacksmiths at work—one striking metal on an anvil while the other steadies it—an image evoking both tradition and the dignity of labor in post-World War I Germany. The stamp was printed typographically by Reichsdruckerei in Berlin on paper with the distinctive diamond-shaped waffle watermark, upright orientation. The perforation is comb 14 x 14¼, and the margins display full printer’s inscriptions, control numbers, and value indicators. Issued in October 1921, this stamp belongs to the first major occupational definitive issue of the Weimar Republic, aimed at illustrating the nation’s economic base and industrial workforce. The choice of intense blackish rose reflects both printing experimentation and inflationary adaptation of the era. It is catalogued as Michel DR 166, Scott DE 145, Yvert et Tellier DR 146, Stanley Gibbons DR 161, and Unificato DR 146. Condition Superb MNH full sheet with strong color saturation, intact perforations and selvage, minor set-off impressions on reverse from adjacent sheets during storage. Estimate "$115 – 140".
