Stamp: Germany – Deutsche Demokratische Republik (DDR) – Commemorative series “250 Years Berlin Academy of Science – Wilhelm von Humboldt”, 8 Pf, carmine‑red, showing an engraved portrait of Wilhelm von Humboldt associated with the tercentenary celebration of the Academy of Sciences in Berlin. (Issue: 10.07.1950)
Postmark: Germany – Commemorative postmark “DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN – 250 JAHRE” – 09.12.1950
Special cancellation created for the 250th anniversary of the Berlin Academy of Sciences. Its commemorative inscription directly relates to Humboldt’s role in the institution, clearly distinguishing it from a standard circular date stamp.
Postcard: Monochrome printed illustration presenting a classical portrait drawing labelled “WILHELM VON HUMBOLDT – Goethes Freunde. IV.” The depiction follows the traditional academic portrait format associated with early 19th‑century German cultural editions, highlighting Humboldt’s likeness in a detailed half‑length composition. (Edition: unknown)
Concordance:
Thematic: The thematic concordance is outstanding, as all three elements focus on the same historical figure and his scholarly legacy: the stamp honours Wilhelm von Humboldt in connection with the Berlin Academy of Sciences, the postcard presents a portrait of Wilhelm von Humboldt, and the commemorative postmark marks the 250th anniversary of the same institution. Together, these components converge precisely on Humboldt and his academic contributions, forming a perfect triple concordance fully aligned with maximaphily standards.
Geographic: The thematic commemorative stamp, the Berlin Academy anniversary postmark, and the cultural portrait postcard are all connected to Berlin, the city central to Humboldt’s intellectual and institutional activity. This ensures geographic coherence in full accordance with FIP maximaphily guidelines.
Temporal: The postmark date (09.12.1950) occurs within the normal postal validity period of the 1950 commemorative issue, ensuring proper temporal concordance for a maximum card produced during the same year as the stamp’s release.
