CBM got their hands on The Avengers movie storybook (yet to be released?!) and posted a bunch of pages.
Lots of images are featured in addition to the following pages giving spoilers and details in regards to the plot and direction of the movie.
I haven't read everything, but I think a lot of it we already knew just based on watching all the various trailers, but there is additional info.
Also, check out the cool pic of Cap on ice.
With that said though - Spoilers!
