Teresa Bellon was born in Albacete, Spain in 1987. She spent a few years wandering around before she did an Illustration Course in Madrid. As a result, she began working for national and international clients and her work has been exhibited all over Spain. Influenced by Portuguese and Nordic illustrators of children's books, her drawings have a touch of naivety, reduced ranges of colors, and simple compositions. Teresa doesn’t stay at home waiting for inspiration, she sets out to find it. So she travels, buys illustrated books, and walks a lot around her home city, Madrid.
