In the 1920s and early 30s, Geller produced many images of traditional Jewish life and culture. His subjects included Eastern European klezmorim playing their instruments against an expressionistic shtetl backdrop and horseradish grinders on Maxwell Street wearing traditional Orthodox garb. According to his publisher and patron, L.M. Shteyn, Geller strove to create a new Jewish aesthetic that would “open the eyes of Jews who have had the misfortune of securing every page of their history with blood.” The Shteyn Farlag published four art albums devoted to Geller's work—each in a bilingual Yiddish-English edition—and at least eight monographs illustrated by Geller.
