It's not a comic book, it's more of a coffee-table art album showcasing the talent of graphic artist Ciruelo Cabral.
It's got dragons in it, many of the images are wall poster quality (or desktop backgound candidates). As a bonus, there's a good selection of text: legends, histories, classifications of dragons, habits, favorite foods, etc. It almost feels life a detailed wikipedia entry on the subject of flying lizards.
What I liked best about the book is how well the translation to ebook was managed (I read it on my iPad). It's a real multimedia project, with background music and soundeffects created by the same artist, with zooming in and out of the high-resolution posters, with animations and video clips included, with high end fonts and hyperlinks active. I have seen in the lat years many examples of poor formatting, poor spell checking and generic covers for ebooks, but Ciruelo and his team demonstrate here how much more can a reader experience in an electronic presentation. A slight disadvantage is the big size of the download, I'm not sure if it is 300 Mb or more, but I expect it is still available in the Apple store.
