Some time ago Koos (Meinderts) translated two books by Oliver Jeffers for Fontein publishers: The day the crayons quit and The day the crayons came home.
I was an immediate fan, they are such funny and endearing books.
In fact, all his books are lovely. And beside picturebooks he makes beautiful covers like the one for The boy in the striped pajamas above, and also free work.
Oliver Jeffers was raised in Belfast, Northern Ireland, but now lives in Brooklyn, USA.
