Issued in August 1921 as part of the “Numerals” definitive series of the German Empire, this 25 Pfennig stamp features a bold numeral design by Willi Geiger, emphasizing clarity and utility during the early Weimar economic period. Printed in bright sienna to vivid reddish brown by typography at the Reichsdruckerei in Berlin, the stamp is perforated comb 14 x 14¼ and printed on paper with an upright lozenge (diamond-shaped) watermark. It measures 22 by 26 mm and was used for standard postal rates in a time of growing inflation. Catalogued as Michel DR 161 (Scott DE 140, Yvert DR 141, Gibbons DR 156, Unificato DR 141), this is a complete mint never hinged sheet of 100 stamps with full original gum, well-aligned perforations, and no folds or separations. A fine and attractive sheet representative of Germany’s definitive stamp production during the volatile early 1920s. Estimate "$170 – 210"
