[1] The following collaborated permanently:[2] Among them stand out: José Carlos Mariátegui, who made known through Mundial his famous Seven Interpretive Essays on Peruvian Reality, before publishing them as an organic book;[2] Luis Alberto Sánchez, who published numerous literary essays; César Vallejo, who from Europe sent his chronicles that covered the most diverse cultural and political topics of the Old World; Jorge Vinatea Reynoso, with the well-made caricatures of him;[3] Humberto del Águila, with his "letters from Rucio", political comments in Cervantes' style.

Without falling into the questionable methods of the yellow press, Mundial knew how to take advantage of that contribution, incorporating sensational and current sections, within a broader content, where opinion, satire and political caricature, interviews, social and labor pages, criticism of shows, literature, etc.

[1] At the end of 1930, Aramburú began a campaign for humanitarian treatment to be given to the overthrown and imprisoned president Augusto B. Leguía, because his advanced age and delicate state of health demanded it.
