Issued in 1949, this Swiss semi-postal stamp was part of the annual Pro Juventute series, dedicated to children’s welfare. The design, created by Hans Fischer and printed by Courvoisier S.A., features Anemone vernalis, a delicate alpine flower with soft yellow petals. The “10+10” denomination indicates a 10-rappen postage value with an additional 10-rappen surcharge benefiting youth charities. With its clean botanical design and deep green background, this issue exemplifies Switzerland’s mid-century floral series—highly sought by collectors of charity and flora themes.
