You would think it is impossible to top getting an Oscar, but Shaun Tan has managed it by winning the world's richest children's literature award, the Astrid Lindgren Memorial Award (worth 5m kroner or A$765,000).  As a comparison, the Man Booker International Prize is worth a mere A$93,620!  The decision to give him the award was anonymous.  The prize (like the Nobel prize) is given for a body of work.  (Who knows, the judges may have looked at the great work he did for Aurealis.)
