A nice expanded lwb essentially. The book goes through both de Gebelin's and de Melletcs lives and essays, briefly, before turning to describing the cards. Place used Aluette cards for inspiration when de Mellet didn't describe their meanings, as he concluded that's where de Mellet got his pip meanings in the first place.

It ends with a nice, succinct description of how to use de Mellet's divination method, including notes on how to deal with the inconsistencies.

If you get the deck -- and it's lovely -- definitely get the book as well.
