A beautifully printed San Marino definitive/commemorative featuring the vivid Hemerocallis hybrida (daylily), rendered in rich red-orange tones by Courvoisier S.A. Known for its clean engraving and soft yellow background, this issue is admired for its botanical accuracy and elegant layout. The crisp L.1 denomination makes it a desirable addition to thematic collections on flowers, horticulture, and European flora. A fine example of mid-20th-century San Marino design, valued for its aesthetic appeal and excellent production quality.
