Collects Giant-Size X-Men #1 (1975) and Giant-Size X-Men: Tribute to Wein & Cockrum #1 (2020) with a ton of extras.

From the publisher:

One comic book changed the face of Marvel Comics forever in 1975!

Writer Len Wein and artist Dave Cockrum revamped the X-Men with an international cast including Storm, Nightcrawler, Colossus and Wolverine! This legendary story took fans by storm and set the stage for the X-Men to become the most popular heroes in the Marvel Universe!

Now, 36 of Marvel's top artists come together to re-create this epic story, each drawing one pulse-pounding page in tribute to a true Marvel masterpiece!

This all-new, all-different tribute is presented alongside Wein and Cockrum's inimitable original - together with behind-the-scenes artwork and more special features - and all on oversized pages that give new meaning to the title "Giant-Size X-Men"!

Written by Len Wein.
