This striking anti-polio charity label was issued by the Elizabeth Kenny Foundation, United States, to raise awareness and support for polio treatment and rehabilitation programs. The design features a child in the foreground and a portrait of Sister Elizabeth Kenny, the pioneering nurse whose revolutionary therapy helped transform polio care worldwide. The bold message “Prevent Polio Crippling” reflects the global public health campaign against the disease during the mid-20th century. Such labels were commonly sold to support medical research and hospitals dedicated to polio patients. Collectors value these pieces as important examples of medical and social welfare philatelic ephemera from the polio era.
