Giant-Size Avengers #4

Few Marvel covers from 1975 capture a moment quite like this one — the Vision and the Scarlet Witch stand at the center of a wedding ceremony, bouquet in hand, as Thor, Iron Man, Hawkeye, and a cast of assembled Avengers bear witness to "the most long-awaited wedding of the decade." Looming ominously above the gathering is a massive, flame-crowned figure, while the cover's own caption warns that the Dread Dormammu may put asunder what has been joined together. Penciled by Gil Kane and John Romita with inks by Al Milgrom and John Romita, this oversized 68-page issue delivers the kind of grand, cosmic romance that only Marvel's Earth's Mightiest Heroes could pull off.
