Issued by San Marino (1969), this attractive zodiac-themed set features stylized constellation artwork designed by Luca Vangelli. The stamps depict Pisces (L.180), Capricorn (L.90), and Aquarius (L.100), each highlighting major stars within the constellations using dotted celestial mapping. The modern graphic design and contrasting dark-background glow effect make this series visually striking and highly collectible among thematic astronomy and zodiac collectors. These stamps form part of San Marino’s popular late-1960s thematic issues known for artistic layouts and excellent printing quality. Well-preserved examples are desirable for thematic albums focusing on astronomy, constellations, or horoscope themes.
