In 1931, Tarsila traveled to the Soviet Union. While there, she had exhibitions of her works in Moscow at the Museum of Occidental Art, and she traveled to various other cities and museums. The poverty and plight of the Russian people had a great effect on her, as seen in her painting "Workers (Operarios)" (1933). Upon her return to Brazil in 1932, she became involved in the São Paulo Constitutional Revolt against the dictatorship in Brazil, led by Getúlio Vargas. Along with others who were seen as leftist, she was imprisoned for a month because her travels made her appear to be a communist sympathizer.
