This elegant San Marino definitive features the Italian Sparrow (Passer italiae), beautifully illustrated perched on a blossoming branch. Printed by Courvoisier S.A., the design showcases fine chromatic detail—particularly the warm chestnut tones of the bird and the delicate yellow blooms. Part of a natural history-themed series, it reflects San Marino’s tradition of high-quality engraved and photogravure wildlife issues. A desirable piece for collectors of European birds, fauna topicals, or classic Courvoisier printings.
