Issued in 1963, this elegant Philippine stamp set commemorates the 100th Anniversary of the Red Cross (1863–1963). Each denomination (5s, 6s, and 20s) features a minimalist design by Koreo, showing a stylized grey sailboat and a vivid red cross — symbolizing aid and hope across the seas. The inscription “100 Taóng Paglilingkod” translates to “100 Years of Service,” reflecting the Red Cross’s humanitarian legacy. A fine example of mid-century modern philatelic design and Philippine participation in international Red Cross centenary issues.
