This 50 Pfennig stamp, issued by Deutsche Bundespost Berlin in 1978, honors Walter Kollo (1878–1940), a celebrated German composer known for his popular operettas and songs that captured the spirit of early 20th-century Berlin. The portrait shows Kollo seated at a piano, pen in hand, composing music. Beneath his image appear musical notes and the title of one of his beloved works, „Berlin bleibt doch Berlin“ (“Berlin remains Berlin”), symbolizing the city’s enduring cultural vitality.

The issue commemorates the centenary of Kollo’s birth and belongs to the series celebrating notable German cultural figures. Its fine engraved design and warm brown-red tone give it a dignified, nostalgic appearance — a tribute to Berlin’s musical heritage.
