Heike Faller and Valerio Vidali collaborate as writer and illustrator, creating picture books for all ages that merge text and image into a continuous narrative flow. Their works include Hundred (2018), capturing what it means to grow older through a distinct emotional moment for each age from 1 to 100, Freunde (2022), exploring the many layers of togetherness, and Wir Alle (2025), connecting family histories with the genealogy of humankind. 

Heike is a writer for ZeitMagazin and an award-winning journalist; Valerio is an internationally acclaimed illustrator whose books have been translated into over a dozen languages.
