Answer
Expressionism, known for its emotional intensity and exaggerated forms, is not commonly associated with Marcel Janco's artistic practices. Janco is primarily recognized for his contributions to Dadaism, Constructivism, and the development of the avant-garde art movement in Romania. His focus on geometric abstraction, the interplay of different mediums, and a rejection of traditional styles distinguishes his work from the subjective and introspective nature of Expressionism.
