The Arrival (2006)

2008 winner: Là où vont nos pères Shaun Tan's immigrant story has no words at all, which makes it the easiest winner on this list to read in any language. A man leaves his family for a strange new country of invented alphabets, odd creatures and baffling customs, so the reader feels as lost as he does. The sepia pages look like an old photo album. It is also a rare winner that works for older children and adults alike.
