(San Sebastián, 1979) 
Olga learnt illustration in the Escuela de Arte 10 in Madrid, Spain. Monstruo Rosa was her first picture book and it was awarded different prizes, such as the Golden Pinwheel Awards to the Best Children’s Book in the Shanghai International Children’s Book Fair or the Triángulo Cultural Award by COGAM (Lesbian, Gay, Transgender & Bisexual Collective of Madrid) for having contributed to the teaching of equality. Olga lives in Lavapiés, Madrid, and combines her work as an illustrator with that of a graphic designer. Her work focuses on the promotion of illustration as a tool for education and the transmission of solidarity and other values.
