Igor Sinkovec was born in Slovenia in 1978. As a kid, he dreamt of becoming a truck driver--or failing that, an astronaut. As it turns out, he got stuck behind a drawing board -- so sometimes he draws semi trucks and space shuttles. Igor makes his living as an illustrator. Most of his work involves illustrating books for kids. He lives in Ljubljana, Slovenia.
