This pair of sepia-toned stamps from Spanish Guinea, issued in 1958, reflects two contrasting themes central to the colony’s mid-20th-century identity. The 10+5 cts semi-postal commemorates the 75th anniversary of the Pro-Indígenas movement (1883–1958), depicting a missionary holding a cross above a group of indigenous people—symbolizing faith and education efforts. The 10 cts companion stamp portrays two athletes in an intense basketball match, celebrating sports and youth activity. Both were printed by the Fábrica Nacional de Moneda y Timbre (FNMT), blending colonial imagery with cultural modernity.
