A good rule of thumb in evaluating these Marvel Age Masterworks is to check the number of creators on the cover. In most cases, the fewer the creators, the better the masterwork. So it proves here. If Marvel so no reason to change the creative team over the 15 issues that this volume collects chances are they were cranking out good stuff. It is a pity that the high quality of the writing and art didn't save the book from cancellation but Claremont and Byrne went on to much bigger and better things.
The book collects the rest of the Iron Fist title (issues 3 - 15) and two issues of Marvel Team-Up (63 and 64) that tie up loose ends leftover from the Iron Fist title proper. Marvel Team-Up was a Spider-Man team up title that was often used for tying up loose ends remaining from cancelled comics. This policy often led to Spider-Man being somewhat out of place in someone else's story. This was the case here especially in Marvel Team-Up 63.
The plots are fast moving and exiting. Picking up from the Colleen Wing abduction in the previous masterwork Iron Fist and Misty head to London to track her down. There is a two issue detour to fight Radion and then three issues to rescue Colleen. Three more issues have Iron Fist and cast up against martial arts gangsters followed by two issues fighting the Wrecking Crew with a guest appearance by Captain America. A one issue fight against Boomerang, another against Sabre-tooth (his first appearance, I believe), and the series wraps up in one of those fun but contrived comedy of errors fights against the X-Men. The two Marvel Team-Up tie up the Steel Serpent sub plot that was left over from the Iron Fist title. There are a few seams showing as Misty Knight's undercover assignment gets dumped without resolution. All in all, hugely entertaining.
The art is great. Byrne is inked by four different inkers and he looks consistent throughout; none of the inkers overpowers his pencils.
There is an introduction by Bruce Canwell comparing Claremont and Byrne to Lennon and McCartney. This is only a slight stretch in my opinion. Extras are limited to five original art pages. Although the individual issue page count was low during this period it still adds up to respectable 288 pages everything included.
Highly recommended. Iron Fist would go on to co-star with Power Man in "Power Man and Iron Fist" but that will likely be part of a future Power Man masterworks series. It is tragic that Marvel's best martial arts hero, Shang-Chi, Master of Kung Fu, is tied up in rights issues. It was one of the best titles Marvel had in the 1970s.
