National and international medical meetings are occasionally marked by the release of a stamp from the host country, and a few stamps have appeared over the years to commemorate paediatric congresses. One of the earliest is from Brazil for the 1st Brazilian Infant Welfare Convention and Paediatrics in 1947. In 1977, India released a single stamp to commemorate the 15th International Congress of Paediatrics held in New Delhi, the stamp depicting a Khajuraho sculpture “Mother and Child”. Two congresses are shown on the 1976 air stamp from Costa Rica—the 5th Pan American Children's Surgery Congress and the 12th Central American Congress of Paediatrics.
