Issued by Italy in 1959, this 15-lire commemorative stamp honors Camillo Prampolini (1859–1959), an influential Italian socialist leader, journalist, and advocate of cooperative movements. Printed in rich carmine-red, the portrait captures Prampolini in his characteristic hat and beard, rendered in fine engraved detail. The stamp commemorates the 100th anniversary of his birth, reflecting Italy’s mid-20th-century tradition of celebrating cultural and political reformers. A desirable piece for collectors of Italian history, political figures, and classic portrait-engraved issues.
