CELEBRATING THE CLASSIC'S 45TH ANNIVERSARY! Forty-five years ago, a comic book came out that would change the face of Marvel Comics forever. Writer Len Wein and artist Dave Cockrum revamped the X-Men completely, replacing the bulk of the teen heroes with a completely new international cast! The legendary one-shot took comic fans by storm and set the series off in a new direction, setting the stage for the legendary X-scribe Chris Claremont to make them the most popular heroes in the Marvel Universe! Now, 37 of Marvel's top artists come together to re-create this epic story, each re-drawing one pulse-pounding page in tribute to this Marvel masterpiece! FINAL COVER MAY VARY. ALLOCATIONS MAY OCCUR.
