Not 100% on topic but today postman brought me a huge Royal Mail blue bag which contained a book I had ordered recently. I didn't realize the book would be so large, but I don't mind. It's printed in excellent quality and it has maps and description of pretty much everything that happened at sea in WW2.
The book is War at Sea - A Naval Atlas 1939 - 1945. Little size comparison to a "normal" book and peek inside:
