Oliver Jeffers' work is some of my favorite among childrens book illustrators and really among any artists. There is a charm that is difficult for me to define. I will just say, whether intentional or not, he's part of the Wes Anderson, Dave Eggers, and Jean-Pierre Jeunet club that hangs out in my brain. Here's a link to his official site.
Following a parade of images is a video in which he describes who he is and where he came from (in a way that only Oliver Jeffers can!) and his creative process. It's long but fascinating.
