The Guidebook to the Marvel Cinematic Universe got it's first look recently with a few covers. The covers shown on ComicVine include Iron Man, The Incredible Hulk, and Iron Man 2.
The guidebooks will include facts for various characters in the MCU. It will also include many different production stills and movie to book caparisons.
The MCU has gotten big so far and there is a lot of material for the guidebooks to cover. With all the Phase 3 putting out new movies, including the hit Netflix TV shows like Daredevil and Jessica Jones with other shows like Agent's of SHIELD, the Guidebooks will be vast and amazing.
