Issued in 1957, this powerful 3¢ commemorative stamp from the United States pays tribute to the scientists, doctors, and volunteers who contributed to the battle against poliomyelitis. The design features a strong allegorical figure holding a shield with the caduceus, symbol of medicine, while standing protectively with two children – a poignant reminder of polio’s impact on young lives. The bold magenta color enhances its visual appeal and makes it an iconic health-related issue. A meaningful addition to any U.S. commemorative or medical-theme collection, this stamp embodies both history and humanitarian progress.
