The timeless classic that changed the way we look at Marvel super heroes celebrates its 25th birthday in style! Kurt Busiek and Alex Ross' original tour through the early history of the Marvels - as captured through the lens of photojournalist Phil Sheldon - is collected in full, together with dozens of pages of brand new commentary from the two iconic creators! Then, Busiek and Ross reunite for an amazing new epilogue featuring the all-new, all-different X-Men in deadly battle against the Sentinels- with the now-retired Phil and his daughters caught in the middle! Plus, a behind-the-scenes look at the creation of the epilogue; scripts, sketches and scores of other bonus features; and a stunning gallery of MARVELS 25th Anniversary Tribute variant covers!
