Another great graphic novel by Grant Morrison and Andy Kubert a must have if your Batman or a Morrison and Kubert fan:
Recommend picking up Superman rebirth issues 1 and 2
Two more comics i highly recommend are Aquaman and Green Lanterns
One of my personal fav comics featuring Lois Lane as Super Woman

Flashpoint comics featuring kid flash and Reverse Flash, issue 3 of Infinite Crisis great front cover drawn in pencil from artist Jim Lee
I highly recommend Dark Knight Returns: The Last Crusade, Action Comics 959 and Batman Rebirth issue 2
Another one of my personal fav comics issue 50 of Green Lantern Corps featuring the Cyborg Superman.
