Particularly, it investigates how this work establishes a dialogue with other models of urban walks, such as the nineteenth-century flâneur and its more recent avatars. From a contemporary perspective, Chejfec confronts this figure with a dystopic version of the city of Buenos Aires, that completely undermines the feeling of control and liberty that has been traditionally associated with flânerie.
