I've got one called "Inside the Titanic," by Ken Marschall, which is a big 32 page 9"x14" kids book which features cutaway drawings of the ship. Its based on the true story of survivor Frank Goldsmith. It's worthwhile, but probably over-priced at $18.95. Don't remember ever seeing a book called "Deep Inside the Titanic."
Sorry to resurrect this old thread but since there has been a lot of discussion lately about Ken Marschall's Titanic art, I felt compelled to mention about this superb book, which I have owned for a long time. I think the pictures are very imaginative and realistic and IMO it is not overpriced at all. I heartily recommend it to anyone interested in the subject.
