"Masterstroke!" Guest-starring Shang-Chi, Master of Kung Fu. Script by Len Wein. Pencils by Ross Andru. Inks by Al Milgrom. Cover by Gil Kane (pencils), John Romita, and Tony Mortellaro. It's the master plan of Fu Manchu! Make Spider-Man and Shang-Chi believe that each other is a criminal, and then set up a super showdown at the Con Ed Power Plant near the 59th street bridge! Even if the web-slinger and the Master of Kung Fu survive their epic battle with one another, the two heroes plus Black Jack Tarr must still stop Fu Manchu at the Empire State Building! A terrific action issue! Back up story: "To Become An Avenger!" Guest-starring the Avengers, Daredevil, and the Hulk. Script by Stan Lee. Layouts by John Romita. Pencils by Don Heck. Inks by Mickey Demeo (aka Mike Esposito). Spider-Man is offered membership into the Avengers, but he has to capture the Incredible Hulk first!
