A dynamic Spain semi-postal issue from the 1961 Pro-Infancia (For Children) campaign, featuring a powerful high-jump athlete clearing the bar in mid-flight. Printed in a rich reddish-sepia tone, the design captures motion and strength, symbolizing youth, health, and sport. The additional +5 cts surcharge supported child welfare programs, making it both postal and charitable. Produced by F.N.M.T., this classic sports thematic fits perfectly into Olympic, athletics, and social welfare collections. A striking mid-century Spanish engraving with strong visual appeal and historical purpose.
