This striking 6 + 3 pesos airmail semi-postal stamp from Argentina depicts the Seibo (Erythrina crista-galli), the national flower of Argentina. Issued as part of a humanitarian series titled “Ayuda a Chile” (“Aid to Chile”), the surcharge of 3 pesos was donated to relief efforts following natural disasters in Chile. Designed by H. Viola and printed by Casa de Moneda, the stamp features fine intaglio detail in deep carmine shades, emphasizing the beauty of the Seibo blossoms. It stands as both a floral and charitable emblem in Argentine philately.
