The Avengers #161 [30¢]-Fair (1.0 - 1.5) Ant-Man Attacks The Avengers.

"Beware the Ant-Man!" Part 1 of 2. In incredible fashion the Avengers are attacked at their Fifth Avenue Mansion! And the assailant is none other than the Ant-Man! What in the world has happened to Hank Pym?!? Fortunately, with help from the Wasp, the Avengers corral their diminutive teammate! But that only buys Earth's Mightiest Heroes a few more hours until the next attacker arrives...a certain adamantium attacker! It's a super showdown inside Avengers Mansion as eight avengers lay it all on the line against Ultron!
