Bookcase?

When is a bookcase not a bookcase?  When it's a book.  This is the rather fascinating cover of a diary that W bought for herself; it's a normal sized diary, but with this very detailed cover of children's books on a shelf.  I'm not sure I read any of them in my youth though; I was more a 'William' and 'Famous Five' fan.

Can you tell I've not been out today?
