Superman: Whatever Happened to the Man of Tomorrow? (Paperback) $7.66 + Free Shipping w/ Prime @ Amazon

"The framing device of "Whatever Happened to the Man of Tomorrow" is the tale of a Daily Planet reporter, Tim Crane, in the then-future year of 1997, paying a visit to former Planet reporter Lois Lane-Elliot, hoping that she, as the last person to have seen Superman alive, can shed some light on the mystery of the Man of Steel’s disappearance ten years previous. The majority of the story is told in flashback, as Lois recounts for Crane the tale of Superman’s final days." ( Source )
