This commemorative stamp was issued by Germany (Deutsche Bundespost) in 1990 to mark the 175th anniversary of the Schwarz-Rot-Gold (Black-Red-Gold) national colors of Germany. The design features early members of the German Burschenschaften carrying the tricolor flag, symbolizing the student movements that championed German unity and democracy in the 19th century. These colors became a powerful emblem of freedom and national identity, later adopted as the official flag of modern Germany. The 100-pfennig stamp captures both historical heritage and patriotic symbolism, making it an attractive thematic item for collectors of political history, national symbols, and German philately.
