CZECHOSLOVAKIA, 1918–1925 – HRADČANY ISSUE: Specialized study of the Linden Leaves watermark varieties on the 1925 T.G. Masaryk commemorative stamps. Presented on two exhibit pages, illustrating eight distinct watermark positions on the sheets. Includes noted printing errors as cataloged in the 1968 monograph C1, each identified by plate number and stamp position (e.g., II/87). A rare and valuable collection for the advanced Czechoslovakian philatelist.
