Elizabet Vukovic is a freelance illustrator born in Rotterdam, the Netherlands, where she still resides. As a kid she had quite an imagination, which she expressed mostly on paper, since acting out her ideas was an annoyance to her siblings. She now devotes herself fulltime to illustration for children and other venues. When not obsessing about art (which isn’t very often) Elizabet enjoys long bicycle rides, traveling, and bugging her elderly cats.
