This complete sheet of 100 mint never hinged stamps from the December 1922 issue of the German Reich’s “Posthorn” definitives features the high-inflation 50 Mark denomination in dark blue-green and magenta. Designed by Wilhelm Szesztokat, the motif displays a central posthorn within an ornate oval frame and typographic inscription, a recurring symbol of state postal authority in Germany’s visual and bureaucratic tradition. Printed during the critical phase of hyperinflation in late Weimar Germany, this sheet exemplifies the increasing need for high-denomination postage, issued just months before the currency reform. Produced using rotary typography (as indicated by the lean lettering and small pointed stars) by the Reichsdruckerei in Berlin, the stamps are perforated comb 14 x 14¼ and printed on paper with an upright waffle watermark. The margin bears plate markings, denomination tabs, and the imprint “Paul & Schwenke, Berlin W.30,” confirming provenance. This variety, distinguished by the colored “Deutsches Reich Mark” inscription, is listed as Michel DR 209Wa, Scott DE 184, Yvert et Tellier DR 203, Stanley Gibbons DR 217, and Unificato DR 203. Condition Mint never hinged full sheet with fresh color, even gumming, and sharp perforations; minor corner blemish in the selvage only. Estimate "$240 – 280".
