Yacaré is a small publishing house founded by Felipe Samper that publishes books with texts by classic authors in a very particular format. He asked me to illustrate two stories by Leopoldo Lugones: La lluvia de fuego (The Rain of Fire) e Yzur, in a reversible volume with two covers. I decided to bring to the final art the marker drawings that I usually make in my notebooks, using four direct inks: a turquoise blue that, added to two fluorescent inks —red and green— and black, allowed me to make interesting combinations.
