This attractive definitive stamp from San Marino features the Golden Oriole (Rigogolo), a vividly colored European songbird admired for its bright yellow-orange plumage. Issued as part of San Marino’s nature-themed bird series, the design highlights fine illustrative detail against a serene sky backdrop. The Italian inscription “Rigogolo” adds regional authenticity, while the clean layout reflects classic mid-20th-century European stamp aesthetics. A desirable thematic item for bird, wildlife, and ornithology collectors, as well as specialists in San Marino issues. Ideal as a single representative example or within a complete fauna set.
