If you were to take a walk through the crowded Jewish neighborhoods of New York, Warsaw, Buenos Aires, and other centers of Yiddish life in the early twentieth century, you would have come across streetscapes full of posters. Theatrical extravaganzas, political discussions, public health talks, literary celebrations—all were publicized in elaborate and striking displays of graphic art. These posters capture a Jewish world that was multilingual and multicultural, eager for escapist entertainment but keenly curious about new ideas and contemporary events. Ranged along these walls is the story of the yidishe gas—the slogans, sounds, and laughter of the Jewish street.
