Concordance

Thematic: Full thematic concordance. The stamp honors Joaquim Caetano da Silva, and the postcard likewise presents his portrait and printed identification. The First Day commemorative cancellation corresponds to the same figure. All three elements—stamp, postmark, and postcard—are devoted exclusively to Joaquim Caetano da Silva, forming a complete thematic unity.

Geographic: Perfect geographic concordance. All components originate from Brazil. The First Day cancel from Niterói (RJ) is geographically aligned with the national scope of the commemorative issue and with the Brazilian subject represented on both stamp and postcard. This establishes a coherent geographic link between the issuing authority, the cancellation site, and the illustrated figure.

Temporal: Strong temporal concordance. The postmark is dated 20 September 1958, the official First Day of Issue for the commemorative stamp. The alignment between the stamp’s release date, the corresponding First Day cancellation, and the matching postcard creates a precise and historically authentic temporal relationship.
