This vibrant 55 centavos airmail stamp was issued by Colombia in October 1963 to commemorate the XXX Campeonato Suramericano de Tenis (30th South American Tennis Championship) held in Medellín. The design, printed by De La Rue de Colombia, depicts a dynamic tennis player in motion alongside crossed rackets over a green court background. The stamp captures the excitement of international sport and Colombia’s pride in hosting this major regional tennis event. It remains a notable item for collectors of sports-themed airmail issues from South America.
