"They Meet" from Superman Confidential #2 (DC, 2007) by Darwyn Cooke and Tim Sale
Superman's answer to Confidential/Classified books enjoyed by other franchises like Batman and the Justice League, it featured discreet arcs by rotating creative teams about Superman's early days, in continuity, but not in sequence, so to speak. Unlike other franchises' more successful attempts, it only managed 14 issues. And yet, people like Darwyn Cooke, Tim Sale, Gray & Palmiotti, DnA and Phil Hester all contributed. Oh well.
