Issued in 1967, this attractive botanical set from San Marino highlights alpine wildflowers growing around the dramatic mountain landscape of the republic. The stamps depict Hemerocallis flava (40 Lire), Cirsium eriophorum (170 Lire), and Papaver pyrenaicum (15 Lire), rendered in fine engraved-style artwork with scenic backgrounds. Flora-themed issues from San Marino are widely collected for their artistic quality and thematic appeal to both botanical and European topical collectors. Complete sets in fresh mint condition are particularly desirable for thematic albums focusing on flowers or Mediterranean flora.
