Issued by the German Democratic Republic (East Germany) in 1964, this 20-pfennig commemorative honors Johann Gottfried Schadow (1764–1850), one of the most influential sculptors of the Neoclassical era. The design features his renowned masterpiece—the Quadriga atop Berlin’s Brandenburg Gate—delicately rendered in deep rose and black. Schadow’s signature is reproduced above the artwork, adding a distinguished historical touch. This stamp is part of a cultural series celebrating major German artists, making it a desirable item for thematic collections related to sculpture, architecture, and German heritage. A clean postmark enhances its authenticity and period postal character.
