This 12 centavos oro airmail stamp from the Dominican Republic was issued in 1947 to commemorate the XIII Pan-American Sanitary Conference held in Ciudad Trujillo (now Santo Domingo). The design features a map of the island of Hispaniola, framed by laurel leaves, with the Caduceus of Medicine symbol at left and an airplane above, symbolizing international airmail. The Latin inscription Pro Salute Novi Mundi (“For the Health of the New World”) emphasizes the conference’s mission to advance public health cooperation across the Americas. A significant thematic issue for collectors of medical, conference, and aviation-related stamps.
