Issued by San Marino in 1967, this attractive flora set showcases three native flowering plants rendered in rich, painterly detail against the dramatic rocky landscapes typical of the republic. The designs feature Centaurea asclepiadea (140 Lire), Hemerocallis flava (40 Lire), and Cirsium eriophorum (170 Lire), each labeled botanically for educational and scientific accuracy. Printed with fine color gradation and strong contrast, the set exemplifies San Marino’s high engraving and printing standards of the period. A desirable complete thematic trio for collectors of botanical, nature, or European 1960s issues, suitable for both specialized flora collections and country albums.
