The autobiographical marks that traverse the poetic work of Pedro Herreros show the gaze of an emigrant who, in difficult economic conditions, adapted himself to living at the beginning of the 20th century during the expansion of modern capitalism in Buenos Aires. The correspondence he had with his close friend, the Argentine cartoonist Antonio Bermúdez Franco, still unpublished, shows some of the strategies that the Spanish poet used to publish his work and be part of literary and publishing circles that would give him the desired recognition. Through both documentary sources, which have served as a methodological guide, we show the difficult economic conditions that Herreros endured and some of the resources he used to make his way into the literary world.
