This vibrant four-stamp airmail series from Costa Rica was issued to commemorate the 1968 Mexico City Olympic Games, celebrating international athletic excellence. Each stamp illustrates a different Olympic discipline—javelin throw, sprinting, boxing, and cycling—rendered in bold colors typical of late-1960s Olympic graphic style. The inclusion of the Olympic rings and the inscription “Olimpiada Mexico 68” highlights the global sporting significance of the event. Designed for airmail usage, the stamps combine sporting imagery with practical postal denominations, making them highly attractive thematic pieces for Olympic and sports philately collectors. Complete sets in good condition are especially appreciated for their visual unity and historical Olympic connection.
