"Tom Landry and the Dallas Cowboys" was published by Spire Christian Comics in 1973 and as you might have guessed from the publisher's name, it's less of a biography of Landry and more of an advertisement of the Christian faith. It starts where all stories should start - Super Bowl VI:
That victory was an anchor point for telling the story of Landry's life. As I said, details are sparse but the highlights include his service during World War II:
His football career at the University of Texas:
His time in New York:
And, of course, becoming head coach of the Dallas Cowboys:
Which leads back to that victory in '72:
The rest of the book centers around his spiritual life. It's hard to sum up a man's life in one comic book but they make a concerted effort to do right by Tom here...and in the end, that's all you can ask for.
