1966 West Berlin 10-Pfennig Brandenburg Gate Definitives Postage Stamp

This is a single used postage stamp from West Berlin (Deutsche Bundespost Berlin), featuring the iconic Brandenburg Gate. The stamp belongs to the definitive series issued in 1966. It is printed on paper with a predominantly olive-green or yellowish-green frame and a grey-toned central vignette depicting the gate in architectural detail. The denomination '10' is visible in the upper left corner, and 'DEUTSCHE BUNDESPOST BERLIN' is printed along the bottom edge. Physically, the stamp features standard perforations on all four sides. The stamp is 'used,' bearing a partial circular black ink cancellation mark (postmark). The postmark includes the number '65' and a date string that appears to include '18.-1.69', indicating a late 1960s usage. The condition shows typical signs of handling for a used stamp, with slightly blunted perforation tips and the aforementioned canceling ink which obscures a portion of the central design. There are no obvious tears or heavy creases visible in the provided image, though the image quality is somewhat pixelated. This is a common but historically significant piece of philatelic material from the Cold War era, representing the postal administration of the Western sectors of Berlin.
