The Avengers #111

In "With Two Beside Them!", Daredevil and the Black Widow join a diminished Avengers team in a desperate bid to break Magneto’s mind control over their captured teammates and the X-Men. With the fate of both teams hanging in the balance, the Black Widow earns her place as an official Avenger in a mission that tests courage, cunning, and the strength of the team’s unbroken spirit. Written by Steve Englehart and illustrated by Don Heck with inks by Mike Esposito, this 1973 classic features a dynamic cover by John Romita, Rich Buckler, and Joe Sinnott.
