This striking 1000 Mark postage stamp from the Free City of Danzig (Freie Stadt Danzig) was issued in 1923, during the city’s brief interwar independence under League of Nations protection. The design features Danzig’s heraldic coat of arms — two majestic lions supporting a red shield bearing a double cross beneath a crown, symbolizing the city’s proud Hanseatic heritage. The bold brown and red color scheme reflects the inflation-era high denomination typical of the early 1920s. A classic issue for collectors of German-area philately and post–World War I transitional states.
