This striking 1969 issue from the Republic of San Marino celebrates the beauty of the zodiac constellations through elegant modernist artwork by David Vangelli. Each stamp highlights a zodiac sign — Aries (Ariete), Cancer (Cancro), and Leo (Leone) — depicted in bold silhouettes against radiant cosmic backdrops. The inclusion of major stars such as Hamal, Al Tarf, Regulus, and Denebola connects philately with astronomy, capturing the mystique of the celestial sky. A fine example of San Marino’s late-1960s design excellence, this set remains a favorite among collectors of astrology and thematic constellations.
