Stamp: Spain, “III Centenary Death Miguel de Cervantes”, dark brown, face value 10 céntimos (Issue: 1916 – commemorative series marking the 300th anniversary of the death of Miguel de Cervantes Saavedra). The stamp features an engraved portrait of Miguel de Cervantes framed within a classical ornamental border typical of early 20th‑century Spanish commemoratives.
Postmark: ESTAFETA DEL SENADO – CORREOS – violet circular datestamp (CDS), dated 13 April 1916.
Postcard: Monochrome printed postcard bearing an oval engraved portrait of Miguel de Cervantes Saavedra, showing him in characteristic 17th‑century attire with elaborate ruff and period clothing. The lower inscription reads “D. MIGUEL DE CERVANTES SAAVEDRA” (publisher not identified).
Concordance
– Thematic: The stamp celebrates Miguel de Cervantes, and the postcard also presents a formal engraved portrait of Cervantes.
This constitutes perfect thematic concordance, as both items portray the same historical literary figure in a consistent artistic style (engraved philatelic portrait and engraved postcard illustration).
– Geographic: The Estafeta del Senado (Madrid) cancellation is geographically fitting: the stamp belongs to a national commemorative issue honoring Cervantes, a pinnacle of Spanish culture. As the seat of national institutions, Madrid is a primary location for commemorative postal marks, ensuring complete geographic alignment.
– Temporal: The postmark date 13 April 1916 falls squarely within the year of issue of the 1916 Cervantes commemorative series, which was released for the tricentenary of his death.
The stamp was unquestionably valid for postal use on that date, providing correct temporal concordance.
