Kirszenbaum's studies at the Bauhaus exposed him to many of the most avant-garde artistic styles including constructivism, expressionism and even early abstraction. His graphic works from this period utilize a strongly linear, angular cubistic style to capture life in the shtetl . His work as an illustrator for local Berlin newspapers allowed him to adapt this style to the social life and morals of the contemporary Berlin population.
