This commemorative issue from San Marino honors Rotary International, symbolizing global cooperation and humanitarian service. The design features a historic medieval gateway and tower of San Marino, representing tradition and civic unity, alongside the Rotary wheel emblem. Artwork by R. Franzoni blends architectural heritage with international fellowship themes. Printed by I.P.S. Roma, the stamp reflects San Marino’s tradition of supporting global organizations through finely illustrated commemoratives. A desirable thematic addition for collectors of service organizations, architecture, and European microstate issues.
