This full sheet of 100 mint never hinged stamps from the 1922 “Posthorn” definitive issue of the German Reich represents the high-denomination 30 Mark value, printed in bright sienna and yellow ochre. Produced using typographic plate printing, as evidenced by the bolder serifed numerals and heavier ornamental stars, this variant demonstrates superior clarity and inking consistency compared to roller-printed counterparts. Designed by Wilhelm Szesztokat, the central motif features a stylized posthorn, long symbolic of organized postal services throughout German history. Issued during the hyperinflationary crisis of late 1922, this stamp reflects the escalating face values required to sustain mail delivery, marking a turbulent yet iconic period in German philately. Printed by the Reichsdruckerei in Berlin, the sheet carries a comb perforation of 14 x 14¼ and shows the standard waffle watermark in upright position. The reverse is clean and evenly gummed, with no signs of hinging. The margins bear guide numbers and the imprint “Paul & Schwenke, Berlin W.30,” confirming the sheet’s completeness and production provenance. Catalogued as Michel DR 208P and Unificato DR 202a, this plate-printed variety is particularly sought after for its visual strength and historical context. Condition Exceptionally fresh MNH full sheet with intact perforations, vivid color saturation, and sharp definition. Minor printer’s ink flaw near left margin and a single marginal edge crease do not affect stamps. Estimate "$280 – 350".
