In addition to Manara's usual luscious artwork, this volume offers some insight into his drawing techniques. As a figure artist, I was particularly interested in the "work-in-progress" pages, showing his ink-over-pencil drawing technique, and also the way that he pencils his figures. I withheld one star in my recommendation, because I'd have liked to have seen some written discussion of his techniques (albeit difficult in a multi-lingual book!). Nonetheless, it's unusual for a successful commercial artist (who actually makes a living from his work, as opposed to professing to instruct others how to do so!) to share even this much of his 'trade secrets'.
Sure: the book is definitely 'adult' in nature. However, since figure artists spend most of their time drawing nudes, that shouldn't be a problem, right?
