Major bummer, one of the greatest figures of the comics artform.
"Spain Rodriguez brought a unique perspective to comic art – a hard-edged outlaw’s attitude coupled with a voluptuous sensuality that also espoused class struggle and a universal quest for human dignity. His characters were die-hard individuals who ceaselessly fought the oppressor, powerful women who demanded respect – by force if necessary, and many of the real people who inhabited his life. He excelled at science fiction fantasy, gender warfare, heroic tall tales, and the dramatization of his own experiences. He also created many non-fiction works on historical figures and events, including Joseph Stalin, Che Guevara, and Lily Litvak, the Rose of Stalingrad. He was a genuine Marxist who fought fairly and with club spirit."
