Mariona Tolosa Sisteré was born in Barcelona (Spain) in 1983. Even as a child, she drew what she saw all around her, with a focus on human relationships. She studied illustration in Barcelona at “Escola de la Dona,” where she found her world through acrylic, pencil, collage and digital techniques. Her passion for illustration led her to becoming a freelance illustrator, and in recent years she has been fortunate enough to work with a wide range of clients: from publishing houses, publishing several books which have been translated into various languages, the press and public institutions, to companies and private individuals, carrying out commissions of all kinds, such as picture books, animations, lettering, posters, graphic image for events, portraits, textile illustration, and any other project that involves illustration.
