Avengers Annual #2
. . . and Time, the Rushing River . . .
by Roy Thomas, Don Heck, and Werner Roth
The story includes flashbacks and previously unknown explanations of the team’s previous trip to the ’40s in Avengers #56, and at the end of the story, Goliath uses Dr. Doom’s Time Platform to banish the Scarlet Centurion back to his time—and we think this is the only time travel that actually appears in the story (apart from the flashbacks). We don’t know what happens to the alternative 1968 (now known as Earth-689, but the traveling Avengers return to the universe that we all knew and loved in the 1960s (a.k.a. Earth-616), with their memory of the whole affair wiped by the Watcher.
