This Masterworks edition features The original X-Men series (later titled 'The Uncanny X-Men' numbers 22-31. For $35, it is definately a great buy. Although Stan Lee ends his run as writer with issue 22 (taken over by Roy Thomas), the stories remain great and Jack Kirby's artwork is impressive, even for 30 years ago.

Unlike the Essential X-Men series, these Masterwork editions are in full color with glossy covers. If you're looking to elarn the histroy of the X-Men or are new to the series and can'ty afford spending the money to buy all the old issues, this is the place to start. I definately recommend getting the first three Masterwork editions and then following up with the Clarement "Essential" books later to learn all the important storylines.
