This Colombian 5 centavos semi-postal issue features the emblem of the Cruz Roja Nacional alongside a powerful monochrome scene of nurses loading a patient into a Red Cross ambulance. Printed by Imprenta Nacional de Austria, the design highlights mid-20th-century humanitarian work and the expansion of organized medical aid in Colombia. The bold red cross contrasts strikingly with the grayscale artwork, making this issue especially appealing to thematic collectors of medical history, Red Cross material, and rescue services. Its clean engraving and historic subject matter give it strong visual and philatelic value.
