This 850-lire commemorative stamp, issued by Italy in 1997, honors the philosopher and political thinker Antonio Gramsci (1891–1937). The design reproduces a page from his famous Quaderni del carcere (“Prison Notebooks”), begun on 8 February 1929, written during his imprisonment under Mussolini. The background shows Gramsci’s handwritten notes, while his vivid pink signature appears prominently below. Issued by the Italian State Mint (I.P.Z.S., Rome), the stamp celebrates Gramsci’s enduring influence on political theory, culture, and Marxist thought.
