Look at Rita Rapp's lovely illustrations in this little Swedish childrens book from 1957. The story by Gunnar Skjönsberg is about a little boy who is searching for the end of the world (the title is "The Journey to The End of The World"). During his quest he is meeting all kinds of grown up persons but none of them know where to find the end of the world. At the end of the story he realizes that the end of the world is just at the end of his road, just outside the town where the green fields are beginning.
I love all the little details and patterns in Rita Rapp's illustrations and they remind me of this book from around the same time.
