Issued by Deutsche Bundespost Berlin in 1973, this striking four-stamp set celebrates Berlin’s modern architectural landmarks of the postwar era. The 20pf stamp features the iconic Philharmonie, designed by Hans Scharoun, symbolizing cultural revival. The 30pf depicts the Jüdisches Gemeindehaus (Jewish Community Center), representing reconciliation and resilience. The 40pf showcases the Regina Martyrum Church, a memorial to victims of tyranny, while the 50pf illustrates Ernst-Reuter-Platz, a hub of West Berlin’s modern cityscape. The series is admired for its clean linework and expressive watercolor style, reflecting optimism in Berlin’s architectural renaissance.
