Cover of the Day: Defenders #43 (January, 1977) Art by Jack Kirby and Al Milgrom

Iron Man #23 - "Buy the Four" (2022)
written by Christopher Cantwell art by Angel Unzueta & Frank D'Armata
Defenders #42 (Conway/Giffen, Dec 1976). Okay, they do make an effort to reconcile this with Hulk… Strange complains that the team is tired after fighting him.
