Avengers Epic Collection, Vol. 3

Collects Avengers (1963) #41–56, Annual (1967) #1–2; X‑Men (1963) #45; material from Not Brand Echh (1967) #5, #8.

Earth's Mightiest Heroes are matched with two of comics' mightiest talents—Roy Thomas and John Buscema—for one of the greatest creative periods in Avengers history.

It's a cover-to-cover watershed: Captain America mixes it up with the Russian Red Guardian, all-new Masters of Evil make the scene, and the sinister Ultron debuts!
