(CBR) Thanks to a smash hit movie trailer, a strong showing at the recently concluded New York Toy Fair and, well, Rocket Raccoon, Marvel Comics' Guardians of the Galaxy are enjoying a newfound -- and long overdue -- notoriety. And with the film landing in theaters on August 1, curious comic book readers and Marvel Cinematic Universe fans alike might want to cram as much of the source material into their noggins.
