“Un tesoro para Martín” (A tresure for Martin) is a tale selfpublished by Libros Molones. At that moment I had the opportunity to be the illustator of the project. It is a story for children between 3 and 6 years old. It aims to help realize the children that everyone has a different understanding of the word treasure, it may be: money, photos, objects or friends and family depending the person.
