First of all, I'll kind of apologise for giving 5 stars, as usually reviews giving things 5 star are just a big fangirly chunk of text that says 'OMG I love it so much it's so beautiful everyone buy it it's the bestest!', but I thought I'd be honest, because it really is very beautiful.
It comes in a sturdy hardback kind of sleeve, which has on it some of the golden designs on the walls of Heimdall's observatory in the film, which is a nice touch.
The book itself is covered with embossed leatherette and the cover features some concept art of the fight between Thor and Loki on the rainbow bridge.
Inside, the book begins to tell you how Thor came about in the Marvel universe, how Stan Lee got his inspiration, and then goes on to say how the comic book Thor was translated onto film, with photographs and lots of concept art developing the aesthetics and costumes of him. Sadly, there is not quite as much detail spent on Loki as I'd hoped, considering that he is arguably the main character, Thor aside.
There is also a detailed few pages on the development of Mjolnir, Thor's Hammer, as well as the other props. If I had to find a flaw in the book (save Loki's brief detail), I'd only really say that it'd have been nice to see some of the actual storyboards, or some concept art of scenes from the film.
Otherwise, this book is a highly recommendable investment, the kind of thing that is just a nice possession to have, even if you don't read it very often. I suppose the price seems fairly steep at first, but I think it's worth the extra cost, and am wanting to buy 'The Art of Avengers Assemble' now~ Who knows, this sort of thing might even go up in value after time.
