Poste San Marino’s 20 October 2026 “Storia Sammarinese” issue continues its illustrated history of the republic with four self-adhesive €1.85 stamps by Cristian Ceccaroni. They depict sixteenth-century invasion attempts, seventeenth-century statutes, the Alberoni occupation and the young Napoleon.

The 122 × 106 mm souvenir sheet has a print run of 20,000 sheets. A QR code links the sheet to an episode of Giuseppe Giardi’s “Storia in Flanella” podcast. Each stamp measures 33 × 45 mm.
