Czechoslovakian 20 Haleru Postage Stamp

This item is a historical Czechoslovakian postage stamp, specifically a 20 haleru denomination. The stamp's central design features the heraldic coat of arms of Czechoslovakia, rendered in a detailed, somewhat stylized manner. The main shield is divided into quarters or sections, displaying various symbols: a double-barred cross on a three-mountain base (representing Slovakia), a crowned double-tailed lion rampant (for Bohemia), and other intricate motifs that are less clear but appear to represent further regional symbols within Czechoslovakia. The overall color of the stamp is a uniform reddish-orange or terracotta hue, with the design elements rendered by variations in shading and line work, creating a relief-like effect. The word 'CESKOSLOVENSKO' is prominently displayed across the top, indicating the country of origin. The denomination '20 HALERU' is visible at the bottom, with '20' appearing on both the left and right sides and 'HALERU' in the center. The stamp is perforated around all four edges, indicating it was intended to be detached from a sheet. Visible condition issues include a dark, horizontal postmark or cancellation stamp across the center, obscuring parts of the coat of arms and the 'CESKOSLOVENSKO' text. There might also be a lighter, circular cancellation mark partially visible on the bottom left. The paper itself appears to be of standard weight for postage stamps of its era. This stamp likely dates from a period when Czechoslovakia existed as a unified state, sometime in the 20th century. The quality of printing appears to be consistent with governmental philatelic production.
