Steranko is a genius.
This book collects all of the stories and covers he made for Marvel Comics except for his groundbreaking run on Nick Fury, Agent of S.H.I.E.L.D., which is collected in its own book. These stories include his run on X-Men with Arnold Drake and Captain America with Stan Lee, as well as a romance story and a horror story.
If you couldn't tell from the opening line, Jim Steranko is my favorite American comic book artist. Ever. His work is always filled with unique storytelling and breath-taking art. All of the art in this book is avant-garde. Steranko's art is incredibly unique and cool, even almost 50 years later.
As someone who wants to make comics professionally, I constantly look to Steranko's art for inspiration in storytelling. If you enjoy Frank Miller's Daredevil or the earlier-mentioned Nick Fury, then you will definitely need to read this book. I am surprised that there are not many artists today who try to tell stories like Steranko did all the way back in the 60's.
