Fantastic Four #183 (1977)

"Battleground: The Baxter Building!" Written by Bill Mantlo. Pencils by Sal Buscema. Inks by Joe Sinnott. Cover by George Perez and Joe Sinnott.

It's the cataclysmic conclusion to the Brute (aka Reed Richards of Counter-Earth) storyline! After rescuing the free-falling Invisible Girl; the Impossible Man, Tigra, and Thundra (along with a revived Sue) charge into the Baxter Building to stop the Brute! While at the same time; Reed, Ben, Johnny, and Annihilus fly towards the Negative Zone portal to catch the Mad Thinker's monster android! Seven heroes and four villains do battle inside the Baxter Building! Who will win, and perhaps more importantly, who will lose?

Very good/fine condition.
