Stamp: Philippines – Commemorative issue “Southeast Asia Treaty Organization – 5th Anniversary of the Manila Pact” – 6 Centavos, green (Issue: 08.09.1958)
Postmark: Manila – Circular date stamp “MAY 3 1960 – PHILIPPINES”
Postcard: Colorized printed postcard depicting the Legislative Building, Manila, presented in a neoclassical architectural perspective with finely detailed façade and landscaped foreground. The lower margin includes the caption “4010.—Legislative Building, Manila, Philippines.” (edition: 9B-H1160)
Concordance:
Thematic: The stamp commemorates the 5th Anniversary of the Manila Pact (SEATO) and features an architectural representation of a government building used during the Congress of the Philippines. The postcard also depicts an official state building — the Legislative Building of Manila. Although the themes differ in purpose (international treaty vs. national architecture), both elements share a clear connection to Philippine governmental institutions, creating a partial but acceptable thematic alignment.
Geographic: Both the stamp and the postmark originate from the Philippines, and the postcard’s subject is likewise a prominent Philippine landmark located in Manila. This ensures complete geographic concordance.
Temporal: The postmark date (03.05.1960) falls within the regular postal validity period of the stamp issued on 08.09.1958, ensuring correct temporal concordance, even though the date does not correspond to the issue day.
