This vibrant commemorative stamp from Greece (Hellas) marks the 50th anniversary of Rotary’s presence in the country, issued in 1978. The bold design features the iconic Rotary gear wheel alongside a stylized “50,” symbolizing five decades of service and community engagement. The contrasting colors and geometric layout give it a modern, eye-catching appeal typical of late 20th-century Greek issues. As a thematic piece, it holds strong interest for collectors of service organizations, international cooperation, and emblem-based designs. Its clean typography and symbolic representation make it a standout addition to Rotary or anniversary collections.
