Often overlooked...

I feel that the end papers in books are a bit of an under rated art form that often gets overlooked.
But they really help to set the style and tone of a book, leading the reader into the story, often in really clever or visually surprising ways whilst creating a sense of anticipation.

These are a couple of my favourites from Ladybird Books.
Both drawn by James Hodgson, the first is from 'Bedtime Rhymes' and the second is from 'The Blue Book of Bedtime Stories'.
