The latest (as of this writing) in the series of Retrofit Comics oneshots, Gray Is Not a Color presents its readers with a humorous – and informative – tale of the author's (high school senior) year working in, of all places, the basement of the The Mutter Museum (of medical oddities!) at The College of Physicians of Philadelphia.  An abundance of playful anecdotes, vignettes, reminiscences, and just plain old stories fill this comic book to overflowing, giving readers quite a bang for their buck.
