This attractive Argentine semi-postal trio highlights national sporting activities, depicting track athletics, diving/gymnastics, and a rowing team in dynamic engraved-style illustrations. Each stamp carries a surcharge (shown as “+” value) intended for charitable or sports development funding, making them desirable both for thematic sports collections and charity semi-postal studies. The clean typography, strong monochrome color schemes, and mid-century graphic style reflect classic Argentine design of the period. Complete sets in fresh mint condition are especially appreciated by collectors of Olympic and sports philately.
