Issued in 1968 by the Republic of San Marino, this 3 Lire stamp features the Penna Rossa (Red Feather), symbolizing valor and cultural identity. The design centers on a vivid red feather set against a refined silver-grey shield background, framed in neutral tones for elegance. Created by Martelli and printed by I.P.S. Roma, the issue belongs to a series celebrating San Marino’s heraldic and traditional emblems. A minimalist yet dignified design, it reflects the nation’s long-standing philatelic artistry and commitment to symbolic representation.
