Maybe it’s the books that I buy, but I don’t see many books with illustrations in them. In books the illustration is a visual indication of where the story is but in the case of older books, I would say the illustration is much more of a labour of love.
These illustrations for “The Tempest” by Arthur Rackham are a great example of this.
I only know of Arthur Rackham as it was his illustrations that were included in my edition of “A Christmas Carol”. There is something about his illustrations that set them apart from other illustrated books.
I would love to see more illustrated books in stores.
