Issued in 1960 by Costa Rica, this meaningful semi-postal Christmas set was produced to support the Ciudad de los Niños (City of Children) charitable program. The red stamp depicts a poignant humanitarian scene inspired by classical art, symbolizing care for children affected by hardship, while the blue stamp shows a sculptural choir figure celebrating hope and renewal. Printed by the Austrian State Printing Works in Vienna, the pair combines social awareness with artistic design typical of mid-20th-century charity issues. These stamps are sought after by collectors specializing in Costa Rica, Christmas seals, and welfare-fundraising philatelic issues.
