Willi Petzold was a German commercial artist, painter, glass painter, and one of the most important poster artists of the 1930s. He stood out for his posters of the Dresdner Years of Exhibition in the 1920s. He designed posters and billboards for the state elections of Saxony in 1930 for the Economy Party and the German People's Party, and for the international hygiene exhibition in Dresden in 1931. During the Third Reich Petzold produced posters for festivals on behalf of the Nazi Party (NSDAP).
During the bombing raid of the Allied Army on 14 February 1945 Petzold lost his atelier and all his properties. After World War II, he designed construction posters for Dresden and promotional posters for the political party CDU and the Liberal Democratic Party (SED) in the Soviet occupation zone.
