Nathalie Beauvois was born in Venezuela, and after traveling through and living in many other Latin American countries she and her family settled in small but beautiful Uruguay. She spent her childhood among books and coloring pencils; reading and drawing have been her passions as long as she can remember. She studied industrial design, together with attending art classes with known private artists. She built a solid graphic design background while working in advertising. After several years, she decided to pursue her childhood dream of being an illustrator. At present she works from home, way down in South America.  Less
