Cap Lives Part 1 of 4. "Captain America Lives Again" Script by Dave Gibbons (Watchmen). Pencils by Lee Weeks. Inks by Tom Palmer. Painted cover by Gene Ha.
The Sentinel of Liberty wakes up in 1964 in an alternate reality! And this time it's not the Avengers who pull his frozen body from the sea -- it's the crew of a German U-Boat! What? Captain America is stunned to learn that the Third Reich still exists almost 20 years after the war ended. And his head is spinning as he's hauled to New Berlin (aka the former New York City) in chains.
