Georg Baselitz is the greatest living painter, says curator and art historian Sir Norman Rosenthal. In this video, Sir Norman describes the poetry, grandeur and significance of Baselitz’s Hero series – imposing depictions of defeated and devastated German soldiers making their way home in the aftermath of World War II. One of this iconic series - Mit Roter Fahner (With Red Flag) - is a highlight of Sotheby’s Contemporary Art Evening Sale on 8 March in London.
