Catharina Valckx has written and illustrated over thirty books and been nominated four times for the Astrid Lindgren Memorial Award. Her books are published in over eleven languages and have won numerous awards. Nicolas Hubesch studied illustration in Strasbourg and lives in Paris, where he works as a children's book illustrator. He is also well known for his comics, which are published in many magazines.
"Netherlands-born Catharina Valckx has a writing style that seems to revel in obliqueness and gentle surrealism, well complemented here by French illustrator Nicolas Hubesch's wobbly-line cartooning. Bruno is a book that blends the mundane and the bizarre to interesting effect and may appeal to quirky primary-schoolers." The Financial Times
