A striking semi-postal airmail issue from Haiti, this stamp pays tribute to UNICEF, combining postage with a 0.50-gourde surtax for social causes. Issued during the presidency of Dr. François Duvalier, it features a finely engraved portrait of Duvalier against a warm ochre background, with the national coat of arms and the motto L’Union Fait la Force. Produced by E.A. Wright Bank Note Co., Philadelphia, the design showcases exceptional mid-20th-century intaglio craftsmanship. A desirable item for collectors of Caribbean postal history, semi-postals, and UNICEF thematic material.
