The book by Hansson has a 2 page Introduction that I can't be bothered to read.
The next chapter is on the structure of the tarot. It breaks the Majors into 3 groups of 7 plus the Fool. For the Minors, it tells you what the suit means, its element, season, astrological correspondence and general characteristics. It also gives you 7 color associations, numerological associations and Cabalistic associations. (The book spells it Cabalah.)
The Majors have a B&W picture of the card and a 2 page description that includes Numeral, Hebrew Letter, Cabalah, Astrological influence, a write-up about the archetype and then classical and modern meanings both upright and reversed. The books doesn't really go into the imagery on the cards themselves.
The Minors have the same size B&W picture of the card and a 1 page description. There is some discussion of the imagery in the Minors. Meanings and reversed meanings are given. There's no differentiation of modern meanings as with the Majors.
The last section is about reading the cards and includes 4 spreads including the ubiquitous Celtic Cross (along with a sample reading). There's a short section on "Tearoom Readings" that's different if nothing else.
Then there's bibliography. 218 pages. Worthwhile? Only you can decide that.
Painting the Soul covers both the New Palladini and Aquarian on facing pages. It contains no interpretations whatsoever. There is a description of what's going on in each card. For example, for the Nine Rods, it says:
A man holding a golden flowering Rod seems to be waiting. He earned his red feathers by his courage in battle. His nine Rods glow under a starry sky.
Then there's discussion about each card and sometimes the image is contrasted between the two decks. 184 numbered pages.
I find the artist's words (when the artist is the creator of the deck and not working from a script given by the author) much more worthwhile than those of an author who appears to have been brought in after the fact to write a book. Your mileage may vary, of course.
