Martin Bustamante is an illustrator and painter from Argentina. At the age of 3 he was able to draw a horse "starting by the tail" as his mother always says. As a teenager he was inspired by fascinating worlds full of colors, shapes, and atmospheres found in movies and books such as Star Wars and Prince Valiant. Drawing and painting quickly became Martin's passions and he began working as a professional illustrator. Martin's work has appeared in several publications from Argentina, the United States, and Europe.
