Issued by San Marino in 1975, this artistic stamp pair celebrates the timeless fresco works of the Italian master Giotto, one of the pioneers of Renaissance painting. Printed by the renowned Courvoisier S.A., the stamps beautifully reproduce details from Giotto’s religious frescoes, highlighting expressive human figures and early naturalistic artistic style. The L.100 value depicts a devotional female figure reaching forward, while the L.500 value features angelic figures rendered with Giotto’s distinctive soft color palette. These stamps are highly appreciated among collectors of religious art, Renaissance art, and classic European thematic issues. Well-centered examples with fresh colors are especially desirable for thematic and art-focused collections.
