The Department issued this 3-cent stamp on January 15, 1957, through the Washington, DC, post office, to honor those who helped fight polio.
Designed by Charles R. Chickering, the stamp features the figures of a woman, a boy, a girl, and an emblem. These symbolize the achievement by the American people and the medical and scientific professions in bringing forth an effective vaccine to prevent paralytic polio. The children represent the youth who benefited most from the historic medical achievement. The Caduceus emblem, symbol of the medical profession and the US Medical Corps, is held in the woman's hand. The wording "Honoring Those Who Helped Fight Polio," arranged in two lines, forms an arc above the figures. In a panel at the bottom of the stamp is "United States Postage." All lettering is in dark Gothic with the exception of the denomination "3c," which is in whiteface Gothic and located in the lower left portion of the stamp.
The stamp was printed by the rotary process, electric-eye perforated, and issued in panes of fifty stamps each. The printing of 120 million stamps was authorized.
