X-Men (Vol 1 1963) Issues 51-100

During the journey of the X-Men through issues 51-100, the series grappled with declining sales, leading to reprints of earlier stories from issues #67 to #93 as a means to stabilize the title. However, a significant revival began with issue #94, marked by the introduction of a new, more diverse team in 'Giant-Size X-Men #1'. Spearheaded by writer Chris Claremont and artist Dave Cockrum, this new lineup included international characters such as Colossus (Peter Rasputin), Cyclops (Scott Summers), Storm (Ororo Munroe), Wolverine (Logan), Banshee (Sean Cassidy), and Nightcrawler (Kurt Wagner). The revitalization of the series was further enhanced by Terry Austin’s precise inks, which added depth and clarity to Cockrum’s dynamic artwork. This refreshed team not only reinvigorated the series but also set the stage for its evolution into one of Marvel’s most beloved and critically acclaimed titles. Key issues during this period laid the groundwork for epic story arcs that would define the franchise for decades to come. Key Issues include; 

#58 - 1st appearance of Havok in costume
